I had/have the same problems..... strange hunting on cold starts, and rough idle when warm and stopped

I have changed: plugs, O2's, TPS sensor, air filter, added grounds

I have cleaned: throttle body, intake

...and none of it really helped. I suspect something to do with either a sensor malfunctioning, some sort of leak in the system, or low output from alternator at idle.

I'd love to know the actual pinpoint of it all though. Maybe I'll have my alternator rewound and stuff for higher output...

Hey Sz,

Haven't seen you post in a long time, good to see you round!

Two things you did not mention there, the coil packs, or the MAF sensor.

In my own case, it was the MAF sensor that fixed the problem, for Gargoyle here, the #3 coil pack was broken.

You should run the diagnostic to see what code shows up. If you have everything cleaned up and tightened down, then the likely suspect is a sensor.

Check the codes. Should be a method written up in the How-to if you have not done it before.

Joe

Question "MYSTERIES of the UNIVERSE"...............

I've tried it ALL! Check my old posts .....on the old similar threads...

The thing that seemed to work the best for me.....don't know if it was just coincidental with (almost total [spontaneous]) resolution of the intermittent rough idle on startup (for few minutes only) problem>>>>>>WAS fuel treatment applications: the best were Berryman's ....Redline.....Techron.....

SORRY.... NO DEFINITIVE FIX ..............
YET!



P.S. I should say....no definitive .....DIAGNOSIS ! ! ! !

Hoping for the best !

Just gave up and ordered a new set of coils. My tech says 2 are arcing, and responsible for the weirdness, and at 11 years young guess it's time to bite the bullet before the wet season really wreaks havoc on her driveability. Hope he's right!

Sputter MANIA 2

HA, I finally got some answers, you guys were helpful in trying, but I ended up going to a different shop, who ended up finding out that it was my cam sensor, my baby runs like normal again. And that Stage two ECUtune Chip, definately worth it, wow. Thanks.

Glad you got her going sweet Junior.

Any shop that can check the diagnostics, and has a technician with half a brain, will find your problem and fix it.

These cars are complex. But they only look like space ships. It's easy enough to find what makes them run poorly.

You've got to....

i had the same problem (not as bad as some of the rest of you) but my car had a small shudder at idle and then while accelerating from a dead stop the car would slowly crawl to speed and be kinda jerky. acouple weeks later i went out to start the car and it wouldnt start, the battery was dead. so i took it to get the battery and the charging system tested, my alternator is low. i had the battery recharged and the car worked fine, but now my alternator is in worse condition and the battery is very low again and the jerky/sputtering is slowly coming back.

I had this problem with dead batteries for years...turned out to be a bad door solenoid..it had stuck open causing many strange electrical problems. Had DOOR SOLENOID DISCONNECTED problem SOLVED!!!!! Testing the charging system WILL NOT reveal a bad door solenoid---of which WILL quickly drain the battery overnight.
Also, make sure to replace that short ground wire (I call it the CHARGING WIRE) that goes from the battery post to the body under the battery. If there's corrosion on this wire, you'll have dead batteries and that dreaded 'clicking' before the engine finally starts.
As for the weird low idle issue..it's unrelated to this since I just started getting this after fixing a bad high pressure and low pressure hose going to the (just replaced) steering pump? VERY strange, but I'm not surprised since I do have worn out cam seals and I'm just getting around to replacing the original OEM Oil Pressure switch (I think this is why my engine light comes on after 5 minutes of driving) from 1992!!
I think my oil pressure switch is plugged up or corroded I'm sure about it.

To add: Someone mentioned about replacing the gas cap that solved their poor low idle issue ( RPMs fluctuate causing the engine to stall or starve for gas) and I did notice that my gas cap stopped 'PRESSURISING' at the same time my poor idle showed up at the same time I replaced my high/low pressure Power Steering hoses... So the issue could just be pressure differences in the lines. Confused ECU?? Anyways, time for a new gas cap!! (They do go bad after 5 years!!)
Gas cap update: WASNT gas cap...still no pressure in gas tank!! Something connected to the EGR must have failed though. Still idles good though and I replaced the Oil Pressure Switch (it had black suit buildup on the blade connector)

@odepaj just hinting here, though it does sound like you may have a loose ground wire (Engine groundstrap) I'd advise replacing the groundstrap (about $5 - 10.00 from most parts stores) it's located near the firewall grounded on the topside of the transmission bell housing..you should be able to see it by peeking underneath the Airbox (Airbox connects to MAF) and check your MAP also (on back firewall above Airbox) these contacts do get dirty I just unplug them and spray MAF cleaner into them (get this at AutoZone) then check for other loose wiring. The wires inside the cab do get loose from years of bumps/rattles...check for loose wiring going to the fuse box inside cabin of car by kick panels above fuse box and also on passenger side there's a small panel going to more wires. I had a loose snap connector on my passenger side before a long time ago cause a rough idle.
EXTRA NOTE: A bad or loose ENGINE groundstrap (not the battery ground I described earlier) can cause (happened to mine once) the alternator to look like it's not producing enough amps.
My .02¢
