Alero :: Intermittent Throttle - Hesitation Occur On 2000 GLS V6
Nov 27, 2012
I have a 2000 Alero GLS V6 with 215K miles. The car has been experiencing intermittent throttle issues where it will hesitate slightly. Immediately after this hesitation the trac control trio of lights come on. I don't think this is the bearing as there is no wheel noise to accompany this. Also the trac control lights don't remain on when you start the car the next time. If this hesitation occurs when using the cruise the cruise control will be disengaged.
I also scanned the car and pulled a P0341 and P0440 code. (cam sensor and evap). These codes have existed for the last two yrs long before the throttle hesitation issue has cropped up so I don't think it is related.

I've got a 2000 accent 1.5, and I keep getting a code for a cylinder 3 misfire, when I change the spark plugs, it runs great for about 50 miles or so, then back to square one again. I just changed the coil pack the other day and there doesn't seem to be much of a difference. It has massive hesitation under heavy throttle, and the check engine light begins to blink if it sits and idles for too long. I've scanned it multiple times and it's always been cylinder 3, so it's definitely set on that one... I'm about stumped on what this could be. Also, the previous owner said that after a hot day of driving, the ECU fuse under the hood will blow out, what could cause either one of these things?

Car is 2013 4dr Golf R with about 7000 miles, APR stage 1 flash, and Carbonio intake. Noise is worse when cold and becomes much more subtle once car is at normal operating temperatures. The noise only seems to occur when I go on and off the throttle, particularly when in 1st or 2nd gear, and does not seem to happen when I go over bumps making me feel that the suspension is not the issue.
I'm scheduled to have GMP in Charlotte install a HS Tuning RSR clutch next week, but if it is a transmission problem, I'll have the dealer try and fix it under warranty first.

(2000 F-350, 7.3L, 205k miles) Over this weekend, I noticed while driving mostly in the lower gears, that there was a slight hesitation with the throttle pedal depressed about half way or less. Seem to get worse as the day went by, but no lights or anything came on. Changed the fuel filter and added a fuel injection cleaner to the tank. Checked the oil and it was low, so I filled it to the correct amount.
Drove it around the next day, and it seemed to be good, until it warmed up some, and continued to hesitate. The hesitation seems as if it's not getting constant fuel, and the truck jerks a little. Once you get up to over 2000 rpms, it goes away. Looking up other reviews on similar issues, most have pointed to the throttle pedal sensor and just changed out the pedal assembly. Before I take it that far, I wanted to see what was the corrective action.

I have had a problem with my 99 Alero for some time. It is a 4 cyl 2 door and there is a hesitation that comes and goes I have changed the plugs,fuel filter and air cleaner and will still do it from time to time. I have also tried different grades of gas and injector cleaner.
It seems to do it most when we are going up an incline just before it shifts when the motor is getting the most load on it but it will also do it when I start it up like it has a miss. As I said this comes and gos and no lights have come on so I'm not sure if it has stored codes.
Recently I have tried Outlaw super concentrated fuel injector cleaner and I have not had the problem for the last week or so?

Lately I have been having some trouble with 2002 Oldsmobile Alero v6. When the car is sitting in park I have noticed that the engine idles roughly, And when I try to drive it, the car hesitates on the acceleration every now and then. Also the emissions light (the orange one) will come on for awhile and then dissapear. At first I though it was dirty fuel injectors so I added some Fuel injector cleaner, but that has not fixed the problem. I was thinking the park plugs may need replacing?

2001 Alero ... I've read about the sensors and wiring on the hub causing the ABS and Trac lights. They come on with the Service Vehicle Soon light, sometimes, when I start rolling.
I had a mechanic look at it, and it was not giving any codes. He tried to turn off the lights with the machine, and they would not turn off. He concluded that it was a computer problem. He said that a ground causes the lights to come on, so it could be a wiring problem.
Why would my lights come on intermittently? Do I have to wait until they come on, then immediately pull over and check the sensor or hub? Is there any way to check this on my schedule?

I have a 2000 Suburban 4wd that has a p0300 code. The misfires are coming mainly from #2 and #7 cylinders. Misfires only occur at idle. over 1500 rpm the misfires disappear. I have put new A/C Iridium plugs in, new wires, and new coil packs on both cylinders but the problem is not any better. All 8 fuel injectors all go to 55 psi when activated and drop to 28 when released. All tests were done with my Snap-On Solus.

Where to find this wiring diagram? I was getting hesitation in my throttle and the EPC light kept going on.. So I did some looking and found that 2 wires pulled out of the plug in the cowl harness... There are like 5 plugs under there, and these 2 wires were pulled clean.. So I cant tell which one goes to which... I know its definitely part of the 4 wires going to my pedal...

So, there is a lot happening with the 3.6 hesitation fix lately. Haven't seen anything addressing the 2.0T hesitation. Mine has terrible throttle hesitation - have this problem with the 2.0T and/or looking for any fix? Love the feeling of making a lane change and almost getting smacked in the rear because of the lag ...

Have any other PP 6MT owners experienced strange throttle hesitation while shifting with a APR 1.2 HO tune? I know what turbo lag feels like, but it is almost as if the throttle position is not being read for 1-2 seconds after shifting.
No matter how hard/fast I shift, I can't get the tires to chirp, even shifting at high RPM. When I watch my speedo after shifting, the needle does not move at all until the delay ends, and of course it moves fast when the boost builds. But for 1-1.5 seconds after shifting, with the pedal to the floor, I would expect some acceleration, even not at full boost.
Even when not shifting, and going from no throttle to medium/full throttle, there is a delay with no acceleration and no significant noise/rev build.
I don't remember this being as pronounced before I was tuned. Also, I had GFB DV+ installed about the same time, but I would expect the DV+ to make this better, not worse.

I have a 2000 Olds Alero that will not start. Has spark, Fuel pressure is 55 and holds steady. Compression is low on some cylinders. It is a 3400 6 cyl. I changed the crank sensor, balancer, cam sensor, plugs, plug wires, and ignition module and coil packs.

I have 3400 engine in 2000 alero (V6 of course). Been having problem with my antifreeze leaking, So I assume the lower intake gasket again(which I have already replace 6 years ago with no problem) but this time after I replace it I notice coffee color oil (antifreeze getting in the oil). So figure I must have done something wrong so I replace the lower intake gasket again making sure I tighten everything with correct torgue. Still the same problem, if not worst. I took the front valve cover off (because I didn't see any coffee color from the back valve cover last time) to see if I can see where the antifreeze is coming from, I can see the the coffee color oozing on the top of the 2 center pushrods and rockers not quite from the gaskets itself (from what I can see) and white steam coming valley (or between the two heads)and notice bubbling on the bottom (not sure if that is normal). Not really into replacing the head gasket, but before I do, I want to make sure first.

I have had my 2000 alero for a few years now and it has been a very dependable car to me until now. For some reason my car just dies while I am driving. But only when driving I can start it and let it run. In my driveway all day and nite if I wanted to but as soon as I get a few miles from home it just dies every time I drive it I have replaced the fuel filter but no change so I changed the fuel pump Car still dies!! Next I am changing the ignition I just don't have a clue what it could be.

Recently had BCM issues, a lot of corrosion in it, so I bought a new one connected it, let the key stay in the ON position for 15 minutes for it to relearn. It had been running beautifully until today. I go to start the car and it starts up then shuts off right away. Well at this time I'm in a parking lot with no where to go so I sit there and try the relearn thing again, didnt work. I happened to still have some electrical cleaner in the car so I sprayed out the key hole and key, removing all the junk I could. Nothing.
I unplug battery and reconnect BCM. Boom starts up. Drive it home and go back out a couple hours later to start it again. Does the same damn thing, starts up and dies. Security system light is on so I do the relearn again, nothing. Unplug the battery only this time and it starts fine, but dies on second try. Do I get a new ignition switch? Every time I unhook battery it starts up first try but nothing after that. Security system is over riding everything. I don't want to sink too much money in to this car seeing as it has 222k miles, time for a new one, just not quite ready yet.

Took my 04 V8 in Monday AM for airbag fault, throttle hesitation, and remote key fob/keyless entry range (lack thereof). Called the dealer yesterday and service rep says airbag and remote range fixed OK, but after TSB for throttle hesitation was downloaded, the car would no longer start. Service rep explained that the shop foreman had worked on car personally for most of day and still was not able to start car.

I finally decided to take my car in to the dealership for this random split second hesitation that mostly happens in first gear. I have 8600 miles on the car and it has done it since the day I bought it. I thought it might have been compressor related from running the AC. I have tried driving with no AC and ESP off and it still does it.
So I take it in and they decided to let the new guy work on my car. I take him on a ride (AC and ESP off) and sure enough it does it nice and strong for him to feel it. I was happy so we went back to the dealership and they gave me a 2.slow rental and I was on my way. 24 hours later they call and tell me, "Ron we believe it might be your throttle body so we're waiting on the regional master tech to get his opinion before we put a $750 part on your car".
I'm like "ok, whatever you say, just call me tomorrow with an update because I don't want it back till it's fixed". They call me the next day to inform me that my brake light switch was faulty ($10.25), they replaced my wiper blades, adjusted my wiper arms and the car was ready to be picked up.
Now that I have it back I can say driving it now that it's acting normal is an adjustment. My mind expect that hiccup but it doesn't happen, at least not most of the time. I'm not completely convinced that this hesitation is gone because I think I felt it happen once yesterday. Time will tell... In the mean time it is 95% cured.

I've noticed that my throttle response is pretty weak. Doesn't seem to just go when ya put the pedal down. I mean it goes but not as fast as i think it should. is this how it is on all our cars? kinda seems like it has a hesitation or something. Anything I could do about this?
