I dont think there is a HUCO brand for the 2.8L engines.

BERU is the only brand I am finding.

You could go EBAY route.

EBAY ICM

The ONLY 2.8L ICM on ebay.

79.99 + Shipping. If shipping isnt too bad , this might be a viable option

alright thanks alot guys ... i'll check it out and make sure that could be a resonable answer to my problem once the codes get read ... exactly what does the ICM do ? ... all i've ever read about is the MAF ...

if you have any friends who has the same model and year of your car, they can help you to find out your problem. you can swap some of the parts such as ICM or maf to find out the problem. you got same as my car but I think you are not close to me.

u sure that your maf is ok right ?

yeah ... before when i had the codes read ... it was the MAF and so i had it cleaned and since then nothing has came up with the MAF that i konw of .... i will find out for sure when i get them read again ... but the symptoms i was getting when the MAF was dirty are now gone ... and its just the nasty idle and miss fires once in a while

ICM = Ignition Control Module - it's the little thing on top of your airbox. 2 bolts and you're done.

I dont think that would cause the occasional misfire though, I have three symptoms on my data
1. erratic idling
2. misfire at idle speed
3. misfire at constant speed

but yours is now and then which points to a wiring issue I could be wrong though (possible bad ground)

Doubt it would cause the occasional misfire too. I agree with the bad ground theory. Check the one on top of your intake manifold.
