missing and stalling

[shelbe67]

I was wondering if anybody else has this problem that could help me. I bought my car fromthe original owner 2 years ago it had 43000 miles and he took excellent care of it he once changed te oil after 300 miles bc he didnt drive it for 6 months and it was time to. well anway when i bought it it had a slight miss i thought nothing of it except maybe just a tune up which i did thoughit did not helpwell now i have been doing more mods and it just amplfied the problem sometimes it feels like it has a slight cam in it whch ouldnt botherme if it did. every now and then the car just stalls for no reason the idle drops alot when i turn the wheel at a stand still. I dont what it is but its driving me nuts any help would be great oh by the way its a 94 cobra intake 1.7 roller rockers,short tubes highflow cat hpipe mac catback cai and afpr

Does it have an aftermarket cam or not? If is is a stock cam you are having idleling issues could just be sensors like your IAC or TPS. Sometimes its as simple as a vacuum leak.
What are more symptoms other than what you mentioned.

no its a stock cam i dont think i have any vacuum leaks i did the intake twice thinking that it might be but it was doing that before i did the intake. i had it hooked up to a friends scanner but it showed no codes

also look at the ACT/ECT (especially) sensors.

Hook up a vacuum gauge. Do a compression test. Clean the MAF/IAT sensors. Check all spark plugs. See if any are running rich/lean. Do you smell fuel under the hood at all?

Also try, just for the hell of it, putting the old air intake setup back on. Could be your computer doesnt like the new positioning of the MAF.

i would think that it was the intake but it did it with the old intake also i will try cleaning the maf and the iat though if thats not it what else?

Could be that the MAF sensor itself has just pooped on you. I had tried many different MAFs when mine was acting up all with the same sensor and nothing helped. Then I switched the actual sensor and it was fine. And yes, I did clean the problematic one...several times with electronics cleaner. Like everything else on a car, they go bad at some point.
