I had a small nitrous pop a few months and now the car would not run. It runs way lean then stalls. I unplug the after market mass then it runs. So bad mass I put the stocker back on and it runs fine. Ok So order a replacement After maket mass 350112-c from Granatells " same as what I had" and it does the same thing runs for a few seconds then slowly leans itself till it stalls. Put the stocker back on and it seem fine. Any ideals? the car seem to run great with the stocker and the a/f seem right also. this is a 02 transam. stock motor untouched full bolt ons. any input would be helpfull. thanks

Keep the stock maf.

Keep the stock maf. Do you have someone tuning your car? If you change mafs and you dont adjust your tune it causes your af to be off. Any time you change air flow in or out of your car you need to have it retuned.

Any mass air flow sensor need to be calibrated and tuned ..

Your car run fine with stock maf cause it was tuned around it not on the new maf

The pop could be the car going lean. Because like stated above its not calibrated. Either get someone to tune ot or just keep your stock maf.

Anytime you change air going into a car or going out it messes up the the A/F.
For example putting headers on, or a bigger maf or throttle body. Any time you have changes like that you need to have the car retunned for that increase air flow.

I don't think that the mail order tune can get the maf correctly
Maf tuning is pain in the *** and take long time
