Hey guys I own a 98 b5 a4 1.8t, long story short, I had cylinder 4's ignition coil go bad on me, and ended fouling all my spark plugs. I changed that 1 coil, while waiting 4 my plugs/coils to come in. So pretty much put about 3 miles on it with the plugs fouled. Today I installed all new coils and plugs, and still have a CEL and that Subaru sound ( it does this in and out and only at low rpms). PO102 and P1240 came up when I checked the codes.
Did alittle search for P0102 and they say cleaning the MAF can help fix this problem. Couldn't find much 4 the other code, but do you guys have any ideas that can help??

 

Bump, any info anybody??????

 

so nobody can help me with my problem?????

 

Have you try to disconect the MAF and chechk for performance? If disconecting the MAF does better with your engine it is pretty likely MAF gone bad.

 

It doesn't really perform better, nor worse, but it doesnt misfire, as bad when the maf is unplugged, as if its alittle more consistent with it unplugged.
So Im gonna clean the maf and see what that does?
does anybody know if a vw maf will fit our 1.8t?

 

Have you access to a Vag Com in order to make a log of it?

 

I wish, I don't have the funds to purchase vagcom just yet.
I plan on spending some time today seeing what the problem is.
Also will a vw 1.8 maf fit our car?
