Question about 2004 Chrysler PT Cruiser

1 Answer

I had engine diagnostic done and still don't know whats wrong

I have engine light on and car hick ups while car was idling so I took to aamco to get free diagnostic. The determination was that I need to pay $158 for a 2 hours diagnostic. The engine code PO138 was not conclusivel enough to determine the real problem that needs to be fixed. I was told I need to do this $158 diagnostic just to get an estimate of the work to be done. The other comment was that the 1-2 O2censor voltage high.

Check engine light on

you would need to take it in for a diagnostic check. it could be as simple as not putting the gas cap on correctly, to having a damaged/worn catalytic converter. only a diagnostic tool would be able to detect what the problem is.

97 eagle talon shakes on idle and bucks while picking up speed and engine light is flashing occasionally

This could be many things from the catalytic converter, to needing a tune up, vacuum hose, fuel pump, injectors or O2 sensors. My advice would be to go to Aamco and get their 89.00 check up. They will diagnose, quote and tell you what is wrong without a commitment on your part. Pretty cheap over all if you are a do it yourselfer and they will gladly fix it for you if you change your mind or just do the parts that you don't want to tackle.

O/d light comes on and car shifts hard

Check the fluid for bad,burnt smell and make sure you have the right amount in it. You check it when warmed up,idling in Park.
Are you sure the engine is not overheating? Make sure there aren't any kinks in the trans.cooler lines or cooler.
If you can't see anything wrong with fluid, take it to FORD and pay their diagnostic fee,usually 100 dollars. don-ohio

Engine turns off when put in gear

Have you had the electronic engine control system scanned/tested for fault codes? it will need to be scanned to obtain the fault codes, this is key to finding out what the problem may be that is causing the stall. The fault code test can be done free of charge by any Autozone auto parts store, Aamco transmission or Kragen/Oriley auto parts store. Ask for a "OBD2" (on board diagnostics generation 2) fault code test. You will also need what is called an active test run of the OBD2 system, this picks up problems with the automatic idle speed system control. You will need the dealer or a good shop to run that test, it is called a KOER (key on engine runing) test, the free test is a KOEO (key on engine off) test.

My engine management light as come on and i lack power what does it mean

Hello. In order to find out why that light is on you have to have your car's computer scanned. AAMCO repair shops and many auto parts stores now scan for free. Do that first. It will tell you why you lack power. Joe

The engine revs up when its is idling

Sounds like either an idle air control valve or a TPS sensor. These items will cause a check engine light to come on as well.. I recommend heading to an AUTOZONE or an AAMCO and you can get the check engine light checked for free. Hopefully you dont live in California cause then you can only go to AAMCO cause AUTOZONE cant do it in California. Good luck
