Toyota :: 1991 Pickup Losing Power - Not Running At Idle
Aug 4, 2015
I was driving yesterday and my Toyota pickup started losing power. If I let off the gas at a stop it would rapidly die. I managed to get it home but had to floor it just to get it going in 1st and 2nd gear, and if it was in neutral it would die without giving it a lot of gas. The only way it will start is if I give it a lot of gas while turning the ignition, and have to keep the RPM's up to keep it running. Looked under the hood while it was running and when I let off the throttle the entire motor would shake violently. Cant tell if it's just not getting fuel correctly or if it blew a head gasket maybe. Seems like it might only be firing on 2 or 3 cylinders.

I have a 1991 V6 automatic Toyota pickup. The transmission has ~230,000 miles, but the engine has been rebuilt and probably has less than 5,000 miles on it. I am having overheating issues in both departments.
Engine overheating: This has started fairly recently. My truck began overheating at idle (usually at longer traffic lights) and would cool down again once I began driving. My coolant was low, I took it to a shop, and they fixed a small leak. Fast forward a few weeks and it happened again, and this time when I turned on my heat full blast to take heat off the engine it blew cool air until I started driving. Took it back, they found no more leaks, and couldn't duplicate the overheating symptoms. They also said the fan and thermostat seemed to be working fine. It seems to happen sporadically, regardless of coolant levels.
Transmission overheating: Firstly, my truck tends to delay/hard shift when I first start it in the morning. Once the engine warms up it goes away for the most part. I took it on a 100 mile trip camping on a fairly curvy/hilly forest highway and the A/T Oil Temp light came on. This has happened before when I took it on forest roads, even after a recent ATF flush. Needless to say I had to stop a few times to cool it off. It felt like the transmission was working too hard at a flat 60MPH (2,500-2,800RPMs). A couple times the RPMs were pulsing like it was switching gears back and forth. The next day driving in town everything was back to working order.
I'm not sure if these two things are connected... but they never happen at the same time. I'm taking it to a transmission shop but I want to make sure they don't try to rip me off unless absolutely necessary.

I have a 1986 Toyota pickup. It's small 2 wheel drive with a stick shift. 6 weeks ago, it started lugging very slightly on hills after I had first started the car (only in the first 5 minutes of driving). Then that stopped, and now it loses power on hills so that I have to keep shifting down and going slower until I'm chugging uphill in 2nd gear at 30 mph. It only happens on long hills with a sustained uphill; smaller ones it keeps speed and power fine.

I have a 91 Toyota pickup. Few weeks ago setting in drive through truck quit when I turned on a/c. This happened coup,e times then next time I drove it ran fine. Then it stopped two days in row after driving 20 min. Truck would crank but shut down immediately. Waited few minutes and cranked and drove home no problems. Now truck will only run few min. Before stopping and if I turn on fan or lights the truck stops. Swapped battery from another vehicle but did not fix. Alternator seems to be charging fine, checked with meter output 14.5 volts charging. Checked for codes and no codes.

'91 Toyota 2wd Pickup, 22R-E Engine. 1 yr. ago out of the blue it would start and idle, but if I give it any gas it would die. Shop had trouble figuring it out, then replaced Mass Airflow Sensor; problem re-occurred after once after this repair, but could not be reproduced at shop. 1 yr. later, driving along and engine quits without any warning. Very hard to start, but restarts once, drives about one more block, dies. Unable to restart; engine will crank and catch, but after about 1 second dies. Tried unplugging Mass Airflow Sensor; no change. Left sitting overnight, next morning it starts right up. Problem seems similar to a year ago, though this time it wouldn't start and idle, it would just start and immediately die. In every instance it was rainy/slushy and cold.

Mine is toyota corolla - 2001 VE model. It has 116K miles in it.
It hesitates nowadays to pickup after a long idle time, say in morning when i start to work or when i leave from work to home(idle time of 8 to 10 hrs). I noticed this problem only during very high temp, say atleast 80F.
Hesitation will be there for 4 or 5 secs and will not move even if i give full acceleration, but after that it moves normally.
Car has automatic transmission and i only see this i put it to Drive(D or D2) and not when i do reverse.

I have a 1981 Toyota pickup. when i start her. she starts fine, but sometimes she will idle fine, and then suddenly refuse to. it seems to be random. i can keep her running if i keep my foot on the gas just a little, to keep her rpm's up. but have to put her into N and keep my right foot on the gas and my left on the brake to stop her when she refuses to idle. when she does this on the freeway, it just sputters and runs rough, but as long as i have the gas on, she keeps going.
I don't know what it is that regulates the idle to keep her going when my foot isn't on the gas. also her serpentine belt is slipping. the one attached to the alternator, i can see her charge voltage dropping when she squeals her belt. that i know how to fix, but i'm wondering if it's that, that is the issue? i was told that, but i don't think her serpentine belt has anything to do with her idling. i was told how to raise her idle on the throttle cable and the Idle screw, but is there something else that regulates her idling?

I've offered to do a basic compression check on a 22R engine, '85 Toyota pickup, which is apparently low on power, won't go above 50 mph. Yes it could be a multitude of things. Chances are it's several of them.
I have not yet heard it run. I'll consider myself lucky if I hear the uneven cadence of running on three cylinders.
My job Tuesday is to screen it for the most obvious things like a clogged air intake or air filter, choke stuck closed, worn spark plugs, etc, and do a simple compression test. I will again try to persuade the owner to take it to the skilled mechanic I've recommended, which he has resisted thus far, even though he's about to set off on a long trip through desolate terrain.
I already suspect low compression based on what the owner has implied, but also wondering about ignition timing and vacuum advance. This is a carbureted engine, so does that mean that it also has a distributor and needs to have the timing set? I have a timing light, but only vaguely remember the procedure...disconnect vacuum line from carb and plug hose leading to distributor? Any marks on the harmonic balancer to align?
Evidently it has a bogus exhaust system too - no cat - making me wonder if there's a problem there. I'm not going to get too deep into this, but if I can at least spot the problem I want to be able to convince the owner that there's a clear explanation, so he'll get it resolved.

I have a 91 Nissan pick up that is just making a clicking noise upon trying to start it. I replaced the battery. The inside light works, radio works, dash clock works, but still just clicking upon trying to start. Is there a clutch safety switch that could cause this, or starter, or ???

Where I should start? My 7.3 is running but losing all power. Pumping the fuel pedle will get it started and it will run for a few then lose everything again. Should i just drop the tank and check the sending unit and intake and filters first then work my way up?

I have a 2006 f250 6.0. the truck has 101k miles and to this point I have had zero issues. I am having trouble loosing power after running at highway speeds. Once I stop and begin to accelerate the truck looses power for a few seconds ,Belches smoke and begins to operate normally. I had an egr code, so I replaced egr and the problem persist. It is intermittent and does not happen if I stay under 50 mph.

I recently bought a 4.2L V6 2003 F150 with only 20,350 original miles. This car belonged to an older gent who barely used it, then passed on about 3 years ago, and truck sat around barely used by anyone. When I picked it up I ran some Seafoam through the first two gas tanks as it was occasionally running rough and losing power. Since then truck has been running incredibly smooth, but in the last few days it is getting harder to start. If I pumped it two or three times it would start OK, but today I have had to pump it while cranking it to get it to start. ( the pumping may have nothing to do with it starting)
I am replacing the fuel filter in the next couple of days, as any accumulated junk that was in the tank or lines is now probably in the filter, but it seems that a badly clogged filter would also give me some problems running, and it runs really smooth once it starts. I get a pressure gauge, (I understand the rails have a pressure test port) what pressures should I expect at what moments?
Turn key on :
Crank engine :
I am brand new to the F150 and trucks in general.

I just picked up a 1991 Buick Regal for a good deal, but already the repair costs to get this thing up to speed are mounting :
Right now I'm dealing with all four tires losing pressure. The 24 year old car still has its original wheels (15 inch aluminum) and I'm assuming that they are losing pressure at the seal. The tires are only about a year old and the stems look okay, so do you think I'm on the right track?
There is one strange part to all of this: The vehicle with its equipped tires is rated at 30 PSI and if I fill them to 30 they are all down about five pounds within a few hours or after a drive. However, they do not lose more than or much more than 5 PSI. The front tires lose more air and lose it faster, but the lowest I've seen them is 23. Is only losing a few pounds of air and not going flat evidence of a seal leak or am I in the twilight zone?

2004 Hyundai Santa Fe 3.5L for about a month has been sputtering/losing power when I come to a stop but keep it in gear. You can see the gauge drop when it sputter. Runs fine if I put it in park at the stop lights which I do because I feel as if may shut off (never has shut off). Replaced the crankshaft sensor and it had no effect. I so notice the same sputter when driving sometimes.

My 2000 corolla has about 180,000 miles and loses power when I put it in gear. But the engine revs just fine when it is in neutral or park. What could be wrong?

The problem began a year ago when the car would randomly lose power while hubby was driving it, and then regain power almost immediately and continue to move forward. Weird. Fast forward a year and the problem is happening more frequently. Couple that with the car taking a lonnnnng time to start up in the morning. One day, it ceases to start altogether. Had a mechanic friend of ours look at it and tell us we need a new fuel pump. Okay, no problem. We paid him for the pump and he installed it. Before I could dance a victory dance, though, as hubby turned the key....the car still won't start. Mechanic buddy takes another look at the car and said the ECM is cracked and needs replacement. Looked it up online and ECM is covered under safety recall. Had car towed to the dealership, waited 2 weeks on ECM replacement, dealer called us up to let us know that....the car still won't start, and looks like we need a new fuel pump.
Mechanic friend took another look at it and said it looks like a bad connection between the pump and made an adjustment to it. The car works! Sort of. Car starts acting funny again. We're driving along and the car is losing/gaining/losing/gaining power, tachometer goes up and down, we hear a funny clicking coming from the dash area every time the car loses power. Last night, the car just refused to start. This morning, it started. After several attempts. Made that fun "verr-verr-verr-verr-verr-verr" sound without the "-rooom" at the end. Since my knowledge of fuel pumps and their casings, ECMs, and the like are limited to this situation, I'd love to know what's REALLY going on with the car. I have a suspicion that it goes beyond the fuel pump situation, but mechanic friend thinks it is the casing or something like that.

My old 1996 Camry with 2200 cc 4 cylinder engine, frequently keeps losing power to the spark plugs. I have changed the fuel filter and the ignition coil. That did not work. I also noticed that the car was starting when I unplug and replug the primary wire plug to the ignition coil. So I have replaced the primary power plug with a six inch pigtail and a used plug purchased from a salvage yard. This is not working either. The Toyota dealer near my house want to replace the igniter and the Engine Control Module just to be sure that these are not the sources of problem. The dealer did not test these parts. So I refused to replace the parts without a proper test. I would like to test these parts. Is there a test available for the igniter and ECM that could be performed. I have access to a lot of tools. I need a schematic and/or test to test these components.

I have a 1992 F-150 straight 6. Several days ago it started running rough and losing power and the trans shifted hard.
I put my code reader on it this morning and it read codes 332 and 334 - Insufficient EGR flow detected and EGR closed valve voltage high...
I have looked for vacuum leaks and found nothing. Is it possible the EGR valve is stuck?

My 91 4 runner, with 192k miles, has very scarily lost power twice on the highway. She gets to about 50mph and then drops to 40, 30, 20 rapidly. First time I had her towed because I didn't want to take the chance I couldn't arrive safely at mechanic. 2nd time, I just sat for awhile with her running, and tried and succeeded to get her to mechanic. First time, mechanic thought there was some boot loose around the fuel line.Second time, mechanic is stumped.
She has new fuel & air filter (and battery + leads); catalytic converter tested fine. Had a tuneup less than 5k miles ago.While I feel safe driving around town, I am terrified of highway driving and need getting it fixed so I can resume highway driving.

I have a a 1995 GMC Sonoma 5-speed 4 cylinder pickup. When I drive this truck for any amount of time and turn it off for a few minutes (0 minutes - 1 hourish) the truck runs really rough for the first minute and almost dies. Then it will start running normally again after I've putted down the road a block or two. A couple of times this truck has died completely after running rough and won't start again for almost an hour afterwards.

I have a 1992 Toyota Camry. It had been burning gas, losing powere, white smoke smoking excessively through the tailpipe, and idling extremely rough, sometimes to the point of dying. It ran ok at highway speeds, but terrible everywhere else. We figured that it was getting moisture into the engine. We essentially did an upper engine overhaul, replacing gaskets and parts as necessary. It ran fine after this, and then three weeks later, started having the same symptoms. I found gas in the oil, changed oil, which turned it to run smoother, but still smoked and died at idle. I found out the clutch fan barely blows. I can't afford to get an actual mechanic involved, but I don't know where to look next.
