Hello
I have trans am LS1

Fuel pump racing changed

Ngk tr55 plugs + msd wires
Ls2 intake + headrs long
Tune

The car shut off ( hard miss ) at 3000 rpm on 1 shift !!!

There is only map sensor fault in stored

Any suggestion ?

Not sure what you mean.....auto or manual?

Car shut off? Stalled? Or misfired?

At what speed/gear?

The trans is manual ,,

Car when push accelerator in (1) shift at 3000 rpm at speed the car begin misfired so hard ( like somebody pull the car reversed) .

I checked the fuel pressure is fine also checked sparks and wires

see how it runs if you unplug the maf and start it that way

Thanx .. I will try

Same problem ,,

People said that try to change cranshaft sensor and crank sensor ,, i just buying camshaft sensor

cam sensor you would get a code, crank sensor it would be different, they make it quit. you are going to check the live data on a scanner for things that are out of spec

Problem solved !!

A problem was in the MAF !!!

I put used mad from camaro and car running like a champ !!

Thanx everybody
