Do check the rail fuel pressure. If off by a good bit the engine won't run, though it may fire with starting fluid. Also check for for intake leaks.

so i got her started runs strong but another problem now is lets say i start the car starts u real low rpms then catch's up and idles fine but when you give it full throttle it just wants to choke and die out but i can rev it to the moon if i go slow ? some one help i checked for leaks nothing what now ? maf ? oh another thing the throttle controll unit under th throttle body if i plug it in or unplug it it doesnt change anyting could that be my problem ?
i can get the car to rev right and run really smooth if i block of like 3/4 of the maf then everything is great till i move my hand ?

Afm maybe. Did u check to see if ur spark pluges are fouled? Ur wot switch shouldn't be the problem.

[e30freak661]

new plugs wires all sensors all new vacuum lines everythign still nothing ahhhhh

[e30freak661]

wot?

[matt0300]

Ur wot switch just puts it in open loop. To test it just unplug ur o2 sensor and see if its still sluggish when u put ur foot down.

[matt0300]

Or closed loop sorry.

[e30freak661]

yeah i unplugged that and made no diff the only thing that changed anything is if i block half the maf so it restricts the airflow i guess and then the car runs great so idk

[jaysee]

my cars pretty much doing the same thing right now.. have you checked for vaccum leaks?

also there is a good write up on testing the afm @
