MAF problem Got a ms3 cam installed and put in along with all the supporting mods and having a little problem when under hard acceleration. I've only gotten on the car really hard twice and both times the service engine light comes on and the car like stumbles and misses and then it won't hold an idle until I get somewhere and shut it off for a bit. Then I start the car and it drives fine after that. I have been told it may be a MAF problem I was just wondering of anyone else has had a similar issue. I am not sure where to start. I only got a TSP mail order tune on it right now temporarily and the car drives just great in slow traffic and when just cruising its only when I lay the hammer down it wants to do this.

Well obviously you need to get it tuned properly....would have thought this was a logical decision when a cam swaps been done.
I'm amazed at how many on here think they can swap cams and only run a mail order tune.

Thanks for the smart *** response...that doesnt help me out at all you idiot I know it needs to be dyno tuned by a good tuner but this seems like more of a mechanical problem to me.
Have you every checked the service engine light to see which code it's throwing? if the lights coming on then it's throwing some sort of code. any auto parts store should have a code reader you can borrow to diagnose the problem.
Also stock injectors? could be running out of fuel up top when at wide open throttle.

Well considering it is a Texas Speed cam and a Texas Speed tune. Even if it is mail order it should be close, if you gave them all the info on your car. Yes every car is different, but it should be close. I'm not expert, but you need to find someone who can scan it. Have you tried cleaning your MAF? Electrical contact cleaner is good stuff for MAFs. I would try that, then if it persists to act up find someone who can scan and tune. You don't have to have it dyno tuned either. You can have it tuned on the street like my car. Oh, my car has a custom grind bigger than the MS3. Hope you get it fixed.

You wish to go chasing your tail, by all means go ahead.
Have the codes scanned. If you have stock injectors, I wouldnt advise going wot anymore as if you are running out of fuel, your going to have a hole in the piston very soon.

Okay? Just because it isn't a dyno tune means it isn't even close to what it should be? Good advice... I think Texas Speed knows what they are doing with a tune when it is one of THEIR cams, even if it is mail order... My car is street tuned with a cam bigger than the MS3, and it runs great. Dyno tunes aren't **** unless your tuner knows what he is doing. I have heard of plenty cars letting go on a dyno, because they weren't tuned correctly.
