'85 century, can seem to get it right

Okay, bear with me.

85 century, 4cly, throttle body.

When we got the car ran good, after a day it had some running problems, step on the gas and it sputters, put new plugs, wires, cap rotor on, still sputtered.

I saw fuel leaking from the carb, took it off and put a new gasket on the bottom to the intake manifold. The carb had a very lot of carbon blocking several of the air, fuel chambers. Cleaned it up, put it back to gether, still sputter, but running a bit better.

Put a new map sensor on, still sputtering.


What am i missing..??

Okay, i took the car down to a shop and had them read the OBD1 codes.

13,21,22,33,34,42,44 were the codes active at the time, can anyone recommend a site to look up the obd codes..??

2 of those were o2, and 2 were tps. Guess i can start with a tps sensor.

Check for a vaccume line off, The Iac valve on the throttle body might also need cleaning or replacing. Air filter, fuel filter, and test your fuel pump.
