Car – 91 Chevy Corsica 3.1 automatic (160,000 miles)
Problem – Car struggles (no power), bucks and eventually stalls on inclines. If I wait about an hour, it will starts up OK and runs until it warms up.
Then it starts all over again – No power when I hit the accelerator while climbing up hills or steep country roads.
Speed drops down to 35-45 an hour, and stalls if I try to go faster.
Work done:
Items Replaced
EGR Valve
Map Sensor
TPS Sensor
Crank Sensor
2 Fuel injectors
Coolant Temp sensor
Catalytic Convertor
Tune-up (Spark plugs and wires)
Ignition Module and Coils (scan code showed problems with it)Components Cleaned and checked
Mass Air Flow Sensor cleaned
Throttle Body and IAC cleaned
Fuel Pump, Relay, Fuse & pressure checked – OKStalling problem is still there.
Any thoughts?

To be honest with your limited tools and resources it might not be a bad idea to have it checked out by a professional. You don’t have to have them do the repairs but at least they can check the transmission and the operation of the lock up clutch in the torque converter for you. About the only test I can think of is to check the fluid level and condition. If you see a lot of air bubbles on in the fluid it could indicate a transmission issue, it could also be low fluid so make sure it’s topped off.
As for checking fuel pressure you will need a fuel pressure gauge and the proper attachments for your vehicle to do so.
