Dodge - Ram - 1500 :: 1997 - Idle Roughly At Warm / Accelerating
Mar 13, 2011
I have a 1997 dodge ram 1500 4x4 with the 318ci engine. 140,000 miles. Fall 2009 I replaced the CAT (old one had broken loose and was rattling around inside) and both o2 sensors. A few months later, when I'd start the truck cold it would idle fine then as it warmed at idle it would run rough almost quit then idle up and run fine all by itself. When started warm it would idle fine then hesitate while acclerating a few times then run fine. No check engine light. Now, about 10 months later check engine light is on (P0138 o2 circuit high voltage bank 1 sensor 2). I have put about 5,000 miles on the new CAT. I checked the wires and connections for damage and found none. Also, new cap,rotor,plugs and wires.

I have a 1999.5 jetta vr6, the CEL is on (p0102 MAF sensor circuit low or something like that...). When i start it up, it often dies really soon after and until its warm it will idle really roughly. I'll have to start it up between 5 and 15 times... Once its warm and about 190 F oil temp it runs just fine, but still has a slightly rough idle.
I have a new MAF sensor coming in, or if there are any other things i should check that might contribute to the problem.

I recently purchased a 1997 Rav4 (3F-SE Engine) with 162000 miles. Overall, it is a great car. The only problem (besides a clutch, which can wait) is that it hesitates/bucks between 1500-2100 rpm while accelerating. This happens usually on a shift change from 1st to 2nd, or while in 2nd and after decelerating to make a turn. This only happens after the engine has warmed up, i.e. the temp gauge is above 25%. When cold, there is no hesitation at all. It just passed emissions testing. Check engine light is off. I recently replaced the TPS (and adjusted it properly), with no change in symptoms. This car does not have a MAF sensor.

We got our first taste of fall weather in Houston this weekend, and with it I've discovered a new problem with my truck. After the engine was up to temp, I noticed that the heater would blow cold air any time I sat at idle. If you rev up the rpm's to 1500-2000, you can feel the air start to get warm again. I'm guessing this means my heater core needs to be backflushed.

We have a 1996 Dodge Dakota SLT that we purchased used. It starts and runs beautifully when the engine is cold; however, if you turn the vehicle off it is difficult to get it restarted and to keep it idling without keeping your foot on the accelerator. The funky thing is that after your "fight" with it a few minutes (i.e., foot constantly on the accelerator), the truck will then start to run correctly and idle correctly until the next time you turn off the engine. We have noticed that on each occasion when we have had this problem, the engine smells EXTREMELY flooded. We've been told its a temperature sensor, any other number of sensors, and now the IAC. If starting by process of elimination with least expensive fix first, what the heck do we replace first?

I have a 97 Chevy K1500 truck that i have been having problem with starting. Sometimes it will start. When it does the idle is rough. When i put in in gear it almost acts like it will shut off. Then it comes back and it drives fine. If it shut it off it may or may not start. I had the distributor cap a rotor replaced. Then I replaced the spark plugs and wires. Still does not start. It seems like it is getting too much fuel. I pulled the fuel pump relay and the truck would start then die out. When i put the relay back in truck does not start. I am not sure what might be the next piece to look at. I was thinking the MAP sensor or the throttle position sensor. So far i have not had any codes come up.

I drive a hot mess of a vehicle. It is a 1997 for taurus that's got more than its fair share of miles on it.My big brother drove this car when he was 16 and I am 22. I am a college kid and I don't do much to my car knowing it will die soon but at the same time I don't have much money to do much. We have a good relationship most of the time and I gladly provide gas and regular oil changes in exchange for transportation.
My car when its warm outside especially idles very rough. So rough that at times it stalls out. It seems to happen most often and to the worst degree when the outside temp is very high and it has been running recently and I'm trying to start it up again. At other times and temperatures it has idled rough but not bad enough to stall. Once I start driving, or moving, its fine. The rough idle makes my car sound like a boat, that's the best way I can explain it.
Why my car does this? How to fix it?

1999 F-150 5.4L. I just removed the clutch fan and installed two electric fans about two weeks ago. The same evening, I took a short drive and noticed the idle was way higher than it normally is. Its idling about 800 to 900 RPM. Now, the weird part.....Startup is normal, as in the idle jumps up for the warmup, then drops to the normal 600 to 700 range. after a short drive, the idle is high and noticeable at a stop.
Sometimes, if I let the truck idle, after about 10 mins or so the idle will slowly start creeping up a little at a time till it hits about 900 or so and will level off. I have tried the IAC, I have tried disconnecting the battery and letting the PCM reboot, I have checked ALL my vacuum lines, I have checked my TPS sensor and voltages, checked my MAF sensor and voltages, fuel pressures, everything I could think of...
I hooked up my scanner (Auto X-Ray 6000) and checked all my running data, nothing really sticks out to me as outta whack. No codes set..

Alright so I have an 03 5.4 with 144000 miles. once it warms up to temperature it has a miss and low end power is low and no fuel mileage gets 12 to 13 if I'm lucky. From idle to 3000 rpm its doggy get it over 3000 rpm it runs great. All new plugs and coil packs. What it could be. When the motor is cold it runs great has most its power.

I recently pulled the head gaskets on my '98 RAM 1500's 360 Magnum and after two weeks of waiting on the machine shop I've put everything back in and to torque specs. After a battle with the starter ending in pulling all the shims I painstakingly marked I got it to fire up. But, it is now idling roughly. I burped the coolant system, checked the oil level and removed some as it was slightly overfilled.
I also had an exhaust leak so I checked torque specs on the exhaust manifold. All of this worked marginally but when I felt comfortable moving the vehicle I found that in gear with the throttle open it would sputter, idling it moves along just fine. The engine is pulling air weakly through the filter and I noticed it is blowing a little white smoke when given gas. My OBD2 reader doesn't pull up any codes, I'm at my wits end.

vehicle 1997 dakota engine 3.9L w/autotrans.
The vehicle exhibits an intermittent high idle. I have replaced the usual IAC stepper motor and checked the tps for proper function, also completely cleaned, inspected and relubed the throttle body and linkage.
According to my Inova 3140, there are no codes and the temperature sensors and tps percentage are reading correctly. Also the battery and charging system are functioning correctly.
I do not have bi directional capability or the ability to monitor any of the pid'sOne other thing is that she also has a slight rough idle, but that could be the 200,000 miles.

I have '98 Chevy PU, 4.3L V6, auto trans. Several months ago I noticed the water pump was leaking so I replaced it and the thermostat. Since then it is very slow to warm up. It takes half an hour of driving to bring it up to normal temp. I have replaced the thermostat, the fan clutch and flushed the heater coreto no avail. I even tried blocking half the radiator with a piece of cardboard, no change. The heater works fine, hot or cold air according to the temp dial on the control panel.

1992 WT pick up 263,000 miles had new head gasket installed valves lapped and tune up it was doing it before and does get better when truck warms up, but still can hesitate at times. When cold you have to feather gas pedal to truck accelerating, you can hear truck motor pop through throttle body but will continue to speed up.

My 02 silverado has started making a bubbling sound when I accelerate. The sound is coming from under the passenger side dash.

I have a 1994 dodge ram 2 wheel drive with a 318. Idles fine but when put under a load it starts surging and bucking at about 1500 rpms. Idles at 1500 no problem only under a load...

I bought this used Dodge Ram pickup. It looks like there were a few scratches in the paint and somebody hit it with some spray paint. It doesn't look horrible, but it would sure be nice to have a nice shiny uniform finish to it. I hit it with some rubbing compound and a lot of elbow grease. There is nice looking paint underneath. I just wonder is there a faster way to take that spray paint off? I'll be at it with a month with the rubbing compound. Maybe a fine sandpaper? I just don't want to damage the factory paint.

I have been working through a variety of problems on my 01 AWM with TIP. Im down to two issues that maybe related but Im not really sure. The car idles very rough once warmed up (idles smoother cold). The other is in the way the car delivers its power. Its a un -smooth, kind of pulses at different times jerky and its inconsistent. There are currently no lights on and hasnt been for almost a year. On the last scan the only code that was stores was P01040 (cat). Here is what I have done so far;
Replaces plugs and coil packs Replaced fuel filter Cleaned MAF and TB New N75 valve New DV Cleaned pancake valve replaced 6 vacumn lines with leaks.
Maybe Im missing something here but I think im pretty much down to the PCV system under the intake. Should I just order a rebuild kit from ECS and dig in?

I have a 2000 Mazda Protege ES (1.8L) with 120k+ miles and an automatic transmission. The car drives well at speed, but when sitting at stops it will shake a little, sometimes worse than others. Often the RPMs drop to below the lowest tick for a split second before recovering, very much like when driving a manual transmission and not pressing the clutch in enough. Even when the RPMs are steady at a stop, it shakes enough to rattle a couple of the plastic parts in the dashboard.
Recent history (some likely unrelated, but I'm no expert):New air hose (one from the air filter to the engine) in September. RPMs were falling at idle more often than they are now, there was a decent sized crack in the hose. RPMs stopped falling as often, but has idled roughly before and after.New radiator and thermostat in April (overheated on the interstate and cracked open).New spark plugs and wires last fall after one cylinder wasn't firing.For the last couple years every fall when it starts to get cold, the alternator belt squeaks and I tighten the bolt a little each morning until it stops (usually after 2 days, maybe 3 - the alternator itself is on a long bolt that adjusts the belt tension).Every 5k miles I have the oil changed with high mileage oil and tires rotated/balanced.
I took it to a garage a couple weekends ago after the check engine light had come on earlier in the week. I reset the computer and the light never came back on, so I lost the chance to have the code read, but there weren't any other symptoms beyond what I'm used to. The mechanics at the shop said they couldn't find anything specific causing the rough idle and suggested replacing some or all of the motor mounts, which are weak. They didn't seem confident that would fix the problem, and neither am I, as I don't see how weak motor mounts would explain the low RPMs as well as the shaking.
