Mod problem

504 370z · 01-07-2011, 08:10 AM

So last night a mechanic and I installed the gen 3 intakes and oil cooler and now the car isn't running properly. It has no power below 5k and it idles at 1k. I've gone over it reset the ecu and still can't find the problem.

Also it's stumbling at 4k

This just in. Revs are fluctuating and car won't rev over 2500

daisuke149 · 01-07-2011, 08:22 AM

Loose connection or big vacuum leak

phantom21 · 01-07-2011, 08:36 AM

Possible damaged MAF sensor?

504 370z · 01-07-2011, 08:42 AM

Maybe a loose connection but I once overed everything. MAF sensors were taken out with care. Car has 6500miles

Dreezy562 · 01-07-2011, 08:44 AM

Cam angle sensor?

Check all of the connections. Make sure the MAF plugs are secure. Check all the hoses.

I agree. You have some kind of loose connection with your intakes. If it were me I would take everything back out and inspect.

by any chance did you unplug the harness from the throttle bodies!?

Not a chance

GZ3 · 01-07-2011, 10:37 AM

so everything looks secure? no visible vacum leaks are around the couplers? pull your mafs out and look for damage to the wires would be my next step

Ok so cel came on. Got codes P010B P006A and P0171

daisuke149 · 01-07-2011, 04:05 PM

P010B and A refer to both your MAF's. so something is wrong there.

p0171 is saying bank running too lean which may be a result of the malfunctioning Maf's.

Clean out the MAF's real quick if you can and resecure them. I cant remember if its possible to put them in backwards but check that.

Did you look up the codes? Did you make sure the intake tubes were clean before installing?
