I just installed the ZZP 3 inch intake and my car's AFR is bouncing all over the place. When getting into it,it starts to run lean. Am I gonna have to mess with my fuel trims. I thought this was suppose to a simple thing...


Also my mods are 42 lb injectors,step colder plugs gapped at .033,2.85 pulley,ZZP 3 in downpipe no cat,OTTP heat exchanger and full 3 in exhaust.

Thanks for the help guys

 

More air = more lean...

 

I know this,but after reading the reviews saying you don't need any tuning adjustments kinda makes ya think.Just seeing if anyone else has had this problem

 

I got a lean code after installing mine but I move a **** ton of air

 

Alright, I will adjust the trims tomorrow. Glad to know my car isn't being bipolar. Thanks

 

yeah, i had to get a tune. its a common thing to pop a 171 code after an intake, especially the 3"

 

When I went to get on it, It feel on its face and riched itself out and sounded like a subaru. I shut it off,turned it back on and just had a CEL on. My buddy had this happen and the dealership said it was in "limp mode". That sound right to you guys?

 

Just tune it

 

Your setup isnt all that dif then mine. I also noticed that my AFRs bounce arround alot after putting on the ZZP3" intake. Im told that it's normal to bounce arround so I dont worry about it. I go lean too, (High LTFTs) I just have a canned tune though, from ZZP, I figured they would have the best info for their 3" intake MAF location calibration or whatever.

 

I just ordered this intake. I already have a full exhaust, GM Stage 1 inj and tune. I hope I don't run into issues, can't get a dialed in tune for a bit

 

I'm gonna do some tuning on it today,and hopefully get it dialed in.

 

Let us know how it goes!

 

its a big as intake, flowing more air, i THINK it would be normal to be running a little lean without a tune

 

maybe I need to regap my plugs to .035 also. it hesitates bad when giving it throttle.

 

Got the car tuned,runs like a damn champ. Throttle response is awesome. I replace my plugs to. Runs top notch now.

 

which plugs did u pick up?

 

NGK irdium 1 step colder... I spoke to soon. Car ran good then started falling on its face again. Was throwing a PO300-random misfire. Replaced the plugs,coil packs and injectors. Doesn't throw a code now BUT it now wants to lean itself out. I adjusted the fuel trim and it still act like its hitting fuel cut. I'm gonna try to adjust the fuel some more but other then that I'm outta ideas.

 

Weird, never had a problem with my ZZP 3" CAI at all, Had it on over 2 months now. I Haven't had a problem with header/downpipe that I Put on few weeks back either.

I had no stage kits till as of yesterday, but I will be tuned.

Maybe someone can help you.

 

Check your intake for leaks, you might have a leak causeing unmeasured air to enter.

 

Id check the MAF out, make sure its not grossssss... Did you handle it with care during install of intake? Wonder if something happened to it.

 

Yeah I'm gonna check out the MAF today. I certainly hope that's it because I'm losing ideas of what it could be. Thanks for the help guys

 

Well check the MAF and cleaned the hell out of it. Still acts up

 

have you cleaned the throttle body recently? Just a suggestion

 

When doing the intake,the throttle body looked really clean. I'm throwing a PO300 and a PO302.. random misfire ,then misfire in cylinder 2. I was getting a misfire before the intake,now its worse.

 

You try pressure checking the cylinder? Any coolant lose? How did the plugs look when you replaced them?
