Stalling...

[karmanarx]

95

just hit 62,500
3rd owner, lots of sitting

in the past 6 months

oil changes
radiator changed (leaking at a seal)
new plugs, new wires, new coil packs
major suspension rebuild
motor mounts
VCRM replaced

and my black saleens fit in there somewhere

car shudders when I start it cold some mornings, RPMs drop low and the car shakes. Only has stalled out once or twice like that. Last night it stalled randomly making a slow turn. took me three tries to restart it

but later on, it was acting totally fine. I took a corner and stepped on it, it climbs great up to 3000, maybe 3200 and goes to shift and then just falls through the floor

No car computer resets, no engine codes. Music kept playing, dead car...

Where do I go first?

Fuel or electric?

I'm going to have to go fuel pump and or filter on this one. You need to do a pressure check at the schrader valve.

^Agreed, go to Autozone and rent the fuel pressure test kit (free to rent, $200ish deposit.)

 

[Raped Ape]

I would go the fuel route also, filter, FPR, and or pump.

 

[karmanarx]

Air intake has been removed and cleaned

fuel filter has been replaced

fuel pressure was tested three times in a row, all holding at great levels

whats the next suggestions?

Car died in the middle of a turn again. Took me three tries to start it, then died after 15 seconds of idling and took me another 6 or 7 tries to get it running again

I had a similar problem ...but only in summer time and only when idling in traffic for a while.
I just replaced TPS today, and will see if that cured it.

I am thinking either your TPS, or IAC might be bad....

 

[NoLimit95]

Just before my 94 blew up, it ran real rough for the first time ever and I know for a fact that it was an injector problem. Don't worry about an explosion, I caused that but might want to check to make sure all of them are getting power or are good.

Like said above, TPS could be it and maybe the IAC
