THis is really strange. In order to sort this out faster i decided to accomplish the following:
1. Purchase, gapped at .032 and install a new set of 6 NGK BP6ES spark plugs
2. Cleaned the distributor cap and rotor with deoxit d5.
Once concluding the above steps, i cranked the engine and left it warming up with the choke lever pulled for 3 minutes, and drove the car. No more sputtering, coughing, misfire whatsoever. No more rough acceleration.
What could have been the cause?? Do the plugs become useless if fouled? Is it normal for them to get fouled during traffic jams?
My car has an airtex 8012sx fuel pump with no regulator as it just pushes 3 psi.
