88 Chevy 2500 2WD, 5spd, TBI, 4.3 with miss

Posted

Hi,

Truck starts fine all the time.

Once it's warmed up, it develops a miss as if its starving for fuel.

Fuel pressure is good. Timing is correct. injectors tested/serviced, fuel filter/plugs/wires changed.

I have an OTC 4000E OBD1 scanner and everything is within specs.

Any ideas would be appreciated.

Thanks.

i had an 88 S15 with the 4.3 in it, great engine, 

ok, that said mine did this to me a few times, once was bad cap/rotor, and the other was the electronic module in the bottom of the distributor. i think they called it the ignition control module. 

one other time i had issues was bad wires right outs the box, and plugs not gaped correctly.

Killer223, 

Thanks.  I will pull the Ignition Control Module again.  I got a bad once already, this one might be suspect also. Appreciate the feedback.
