Question about 2002 Chrysler PT Cruiser

Runs rough under 1,000 rpm

Put new timing belt in and now has rough idle under 1,000 rpm. runs great at all speeds above 1,000. If intake timing was advanced by one tooth would this be the results of that?

Maybe timing marks were not set correctly.maybe off by 1 tooth.this will definitely make it run rough and also lose power too.might want to check timing.hope this info helps.take care and good luck, manny

2000 ford escort 2.0L. plugs, wires, coil pack, alternator, MAF sensor. hard to start and RPM around 1k wants to die (any stops) always runs rough. Says air intake sensor. catalytic converter or CCRM?


Have you cleaned the throttle body and throttle body valve? have you cleaned the idle speed control air bypass valve? are the injectors clean? Are there any fault codes in memory, do the things I mentioned if you haven't already. Also hard engine mounts can cause roughness at idle. Another thing is the timing belt tight?

Making whistle noise on off on run and stopping.


There are basically two types of whistle noises.

* Whistle when you get more gas (increase RPM, put gas pedal, sometimes just idling but louder when you put more gas)
This usually intake-side leak.
Intake manifold itself, intake manifold gasket (most likely), even airfilter housing, Airflow meter housing (connector), anything where air goes to engine.
usually engine get rough or unstable idle when intake leak occur.
Engine knocking or pinging may feel.

* Whistle when you decrease RPM (engine brake, reduce speed, sometimes just idling but louder when it dropping RPM)
This usually Vacuum-side leak.
There are many vacuum hoses in engine room. even inside of cabin (heater control, etc)
Try to spot where it coming from.
Vacuum also connected to Brake servo, heater control and spark timing.

Put metal or plastic pipe (small PVC pipe will work fine) to one of your ear then isolate source of noise and find where it come from.

P1299 code after replacing the plenum gasket. Rough and sometimes erratic idle.


This code indicates a large vacuum leak. You can sometimes find a leaky gasket by spraying ether on the gaskets while the engine idles. If the engine changes speed while the gasket is sprayed, you have found the leak.

High --1600 rpm ?? rpm idle


The normal idle speed is below 1,000 rpm...between 800 to 900 rpm. I suspect that the idle-air control motor has seized and can no longer automatically adjust the engine's idle speed. This part is also responsible for slightly increasing idle speed when the airconditioning is switched on to compensate for the added engine load. Some cars even have a "step-up" solenoid to increase idle.

When replacing the idle-air control motor, remember to clean the port that IAC motor goes into; there will be some carbon build-up that may prevent the part's cone-shaped valve from seating properly. A can of intake valve spray helped along with some Q-tips works well.



Hope this helped.

Have a great day !!!

Idles rough and acts like its going to die then revs up....acts like its not getting gas sometimes....when under pressure the air blows out of the defrost instead of the panel


you have a vacuum problem, I would have the intake gasket checked or you can spray carb/choke cleaner around the intake where it meets the heads and if the rpm of the motor reacts then you have a leak, my explorer was the same way, idle raised and lowered,idled rough, stalled, and my vents acting up. new intake gaskets a month ago and wham runs great. My yukon i did 2 days ago as it had the same actions and yep it runs great now. I'm sure its your intake.

1992 Lumina Backfire - I have a 1992 Lumina Euro, 77K miles, 3.1 V-6. Under moderate to hard acceleration the engine will backfire and you can smell gas. The spark control module, coils, wires, plugs,...


I know you mentioned the EGR valve has been replaced, but you may have a bad 'new' part. I know the car is electronic, but has anyone checked its ignition timing (timing belt been looked at, I know it only has 77k on it). Is the fuel pressure regulator OK and it vacumm supply?

Rpms Too Low


the idle speed is controlled through the on board fuel injection control module (known as the PCM), even if u raise the idle at the throttle body the computer will slow it back down, however there is a problem that causes slow idle, do the following procedure to correct the slow idle issue, follow it exactly.

Here are some of the causes of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
