hello i have an '93 oldsmobile cutlass ciera s 3.3 litre with about 160,000 on it. after experiencing some engine hesitation when first accelerating i put new plugs, wires, air filter, fuel filter, sending unit, O2 sensor, vacume lines, cleaned injectors, it got to the point that the car wouldn't move without unplugging the mass airflow sensor. New MAF didn't fix the problem, the car is still undriveable without the maf sensor unplugged. has anyone experienced this problem/ have a solution? plus the obd doesn't set off a code untill the maf is unplugged. i don't think it has map sensor, maybe the tps? Anything would help thanks.

 

so yeah its the tps 200 dollar lesson learned.

 

ok so three maf's, new knock, tps, filters, o2, fuel sending unit, computer, and a punched out cat, and the car still isn't working. it also has new plugs and wires and i cleaned the injectors and fixed any bad vacuum lines. anyone have any ideas?

 

In previous posts you said that you replaced the mass air flow sensor and other parts, did you check the resistance at the maf connector?

 

have you done a cylinder pressure check?
