tbi 350 dumping too much fuel
i put a 92 tbi 350 in a 89 jeep wrangler run good when i first drove it but now its dumpimg too much gas it wont idle right it loads up and #8 plug is wet with gass all sensors check good put new fpr on it and also out a new temp sensor on it the only thing i have not replaced is the injectors any advicewould help ive only been running the motor harness i dont have the vehicle harness but it ran fine before :confused:
The fuel pressure too high? you have the jeep pump, in tank, for the multi point injection ...right.
I agree the FPR should only keep the pressure at the required 12-13 lbs for the tbi, regardless of the pumps capabilitys. Maybe the return line is blockked or pinched? that would shoot the fuel pressure up a lot.
If an injector was leaking on a TBI you would have 4 cylinders getting to much fuel
Have you checked the Fuel Pressure?
have you looked at ALL the plugs?
my experiance is that it could be maf sensor either wrong vacume or its bad,also temp sending unit. both not to spendy to replace,
