My MAF was bad for about 2 months. Drove her easy. I just replaced the MAF and out a new air filter on it a few weeks ago. Ive still been driving pretty easy on her. I have noticed the few times I've gotten into it at high RPMs is will slightly sputter or hesistate. Any ideas on this? I did go into limp mode quite a few times when my MAF was bad. Maybe change the plugs? Or am I possibly running lean and gettin some detonation. Any advice guys?

BTW its a 06 SS/SC with a 2.9 and 42s and a intense tune

 

Have you tried cleaning the Throttle Body? this is a very very common thing to do with this issue and 9/10 resolves it. Especially with a new air filter. shouldn't take you more than 15 minutes. 4 10MM bolts and a sencor and the tb should come right off. Goodluck!

 

and your tune could be the issue. Meaningit could be off i dont care who the tuner is. I can tune a car and 3 months later itll be of by 10%, which is usually caused by somthing the driver did, like clean the air filter, clean the maf, ect. if you had a bad maf when tuned itll be shitty when driving after replacing it since it was tuned with the bad maf. if the maf was good when tuned then went bad, then disconnect the battery for 10-20 mins and reconnect it, and all should bewell

 

It was tuned years ago with a good MAF. I also disconnected the battery for about 2 hours when I was installing the new MAF and new filter. So maybe just clean the thottle body? I wonder who around me would look at my tune.....

 

Does it feel like a rev limiter at all? What are your plugs gapped at?

i am coming up to indy here soon to tune 2 cars if you want me to revise your tune, get new plugs, ngk only, clean the throttle body and ect.

 

Trust me on this one.... Replace your plugs!

 

yea I'm thinkin I need some new plugs. These NGKs have been in there for awhile plus with my car going into Eng Pwr Reduced mode all the time there for awhile it may have fouled one out.

I would love for you to revise my tune! Just PM me when you are gonna be up this way. Thanks man!

 

Sounds like spark blowout.

Check the gap on your plugs. Replace if worn out.

 

r u running one step colder? if so i change mine every oil change.... its a lil excessive but for 7-8 bucks i dont have to worry about them missfiring

 

yea 1 step colder

 

This.

I had the same issue after I put on the TVS (with new plugs). Just popped 'em out and gapped them tighter and I was good to go. If yours are old replace them and gap them tighter, if not just gap them tighter.

 

Yeah get new plugs and gap them tighter. I prefer .032 for a gap. If that doesnt solve the issue you should check your injector insulators for a torn O-ring

 

When I had this issue on my lsj it was a bad injector, like infra said check the injector o ring as well.

 

damn been so long since I installed my stage kit with the NGKs. what do you guys recommend for a gap? With a 2.9, 42s and 1 step colder plug?

 

so a little quick studder or hesitation at high rpms couldnt be a sign of a little detonation? thats what im mainly worried about. dont wanna hurt her

 

Sounds like spark blowout. I'd check the plugs as suggested and then check for fuel.

 

Plugs, same thing happened on my car years ago.
