Do a tune up.. Plugs, wires, pcv valve, oxygen sensors, fuel filter, air filter..

This should smooth things out..

Have a great day !

2002 Buick Century Limited 3.1L rough idle and P305 code shows up


You have an interference motor. If you had to replace the heads due to the valves possibly touching the motor, you have to consider rechecking the compression after you replaced the heads. I had the same motor that had an intake leak. I found frozen rings on the number 1 piston as well as a bent pushrod. Ultimately, the camshaft had broken due to coolant getting to the bearings. If the spark is good, the fuel is good, then the only other problem you'd have would be compression.

I have a 2000 TL as well. Had a VERY similar situation. It wasn't a constant problem and ran fine between times just like you said! Frustrating!
It wound up being ONE coil that was starting to fail. www.acurazine.com is a wealth of info.
Bought one coil and held onto it until next time it ran bad, then went around the rows swapping out the old coil for the new one... one at a time, until it ran right. Then I knew I found the bad coil.
Don't know if this helps, but sure hope it does!

1998 WINDSTAR CSERVICE ENGINE SOON LIGHT IS ON


it's not likely a bad o2 sensor would cause it to run rough, but the catylitic converter, which is what the o2 sensor reads the flow of, would cause the car to idle and run rough.If you take it to an auto parts store to have a diagnostic test ran on it( most major parts stores will do this for free), thecodes it gets would help pin point it alot better.

1988 Ford Crown Vic Strange Idle


When you turn the key on does the check engine light come on? If not it may be burned out. It sounds like a MAP sensor or an O2 sensor is bad. I would suggest taking it to autozone as they do free diagnostic and seeing if a code comes up. If it is a sensor it should, if not it may be the idle sensor not reading right in the ECU. More than likely it is one of the sensors though.

I think your 88 mustang contols the fuel air mix with a manifold absolute pressure sensor. Ive seen were the vacume line going into one has worked loose or broken cousing rough idle and throttle. llso check that the idle air control valve isn't plugged up with soot. This would also result in rough or loping idle but would be fine once the engine is hot. Let me know if this was helpful, good luck.
