Possibly have two plug wires crossed or a bad injector. when running engine unplug 1 injector at a time until you find the one that is not hitting. remember to unplug the iac so engine doesnt rev. when found injector use test lite across wires and run. if light flashes then bad injector. if light stays on or no light then wiring or computer.

Running rough


A blinking or flashing check engine light indicate misfiring. I suggest you check the components of your secondary ignition system especially if it worsens when it's damp.

Check engine light flashing running very rough especially on acceleration


The flashing light usually means the problem is serious enough to damage the catalytic converter. Have you checked the engine computer for trouble codes yet ?

Not running on 4 cylinders . changed coil pack injectors new leads unplug tps sounds a little bit better plug back in an runs very rough


Check each cylinder using a timing light.
Check each cylinder using a noid test tool
If the light flashes while the engine is runing the spark to the cylinder is good.
If the noid lights up while the engine is running the fuel injectors are good.

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.

Engine light is flashing on, and is running rough!


WHEN THE LIGHT IS FLASHING IT MEANS THAT YOU HAVE A MISFIRE. I SUGGEST YOU REPLACE PLUGS AND WIRES. BECAREFUL DRIVING BECAUSE ALTHOUGH UNLIKLY, IT COULD BE MORE SERIOUS AND CAUSE A FIRE
