Question about 2003 Chrysler PT Cruiser

1 Answer

Check engine light comes on, flashing, and the engine runs very rough...almost like it drops a cylinder. Auto shop has been chasing various codes for 3-weeks now. They think they get it fixed, but the

The mechanic has been working with the Chrysler Tech Line, and has so far changed the plugs, wires, coil, crank sensor, and has removed the entire wiring harness and has checked each wire to be sure there is no broken insulation or bent pins on connectors. One time, the codes suggested the computer be replaced, but the mechanic didn't want to change it due to the cost, and the fact that the particular code only came up once. Any thoughts would be appreciated...

Do a compression TEST on all cylinders first

    If this were a compression problem, would the engine run fine after shutting it off for a while? This is the bugger of it. The mechanic has only actually seen the issue a handful of times. It typically takes about 80 miles to act up, then when the engine is stopped and restarted, many times the issue goes away for another 80 miles.

2006 Kia Optima LX V-6 Engine light flashing engine running rough

A flashing check engine light means FIX IT NOW! It probably has a dead cylinder (most likely an igniton issue).Most likely,the PCM has figured out which cylinder it is aand turned off the fuel injector to it.You can get a cheap,basic code scanner(mine was 50 bucks at Harbor Freight Tools,made by Cen-Tech).It can read the code and has a book to tell you what the code means.If you find the cylinder with the misfire and correct the problem,you have to clear the code to restore fuel to that cylinder(this cheap tool does that,too).

I have an 02 Chevy Trailblazer & the Service Engine Soon light is on & flashes while accelerating. Also has a very rough idle. Any idea what the problem may be? Thanks

Rough idle can be caused by dirt in throttle body or EGR system, but there are many other possibilities. The service engine light indicates the computer has detected a fault. If you can get a free scan at your local parts chain and post the trouble codes to us we can give you more specific repair recommendations.

Check engine light on did check and said injector cercuit open cylinder #2 car is running rough how do you fix it?

Code P0202??
Most of these problems occur because of electrical: wiring or ground problems. Before throwing money out and chasing the problem:
Check the wiring harness for Cylinder #2 Fuel Injector. Especially check the Ground wire connection on the intake manifold.
Is the Battery fully charged? The sensors and control unit runs off the battery. If the battery is not fully charged the engine will run rough.

Check these first and get back with me if it does not work.

Hard shifting, ilding rough check engine light flashing

If the CK ENG light is flashing, that means its running bad enough to damage the cat converter. Have that checked ASAP.

Very Rough running engine

I think the auto-lite plugs are probably your problem. yes it sounds like mis-firing. That's one of the few times the check engine light flashes. I'd suggest changing the plugs to a NGK plug, that's the ONLY plug we use in our Audi's and VW's (work at a VW/Audi shop). Try that, and it should take care of the rough running, if not, it will probably need coils too.
