Problems with my 93 cutlass ciera

I had your exact problem. Did wires, plugs, coils, ignition control module, air filter, fuel filter, fuel pump, all 6 injectors, coolant temperature sensor, idle air control valve, cleaned the throttle body, cleaned the maf sensor, o2 sensor, pcv valve, cleaned all the grounds and got a new alternator and battery, ran some Seafoam, and had all those issues...... But I fixed it..... I took off the connector for the crank sensor, cleaned it, and put it on firmly. All issues gone after that one thing. I bought a new connector, but I haven't put it on because its driving like a new car--i mean, half the parts are new now. So I'd try that.

And the injectors on these cars are known to fail electronically. They're quite easy to change out, but make sure the engine is cold. And don't cheap out on the parts.

where is the crank sensor located??

I have a Oldsmobile Cuttlas Ciera 1996 3.3 V6 and the reader scanner showed me a service code 43 EST circuit -low voltage .what does it mean

93 cutlass ciera 3.3 liter engine, tuned up engine, then got some coolant coming out of exhaust pipe & lifter noise & a banging noise like a valve on or cylinders 1,3 & 5.
