Sputtering

[dis_jaydeem_ej2]

ok guys, I have a b16a2 mid built and my car just recently sputtering really bad. I change the motor oil, did a basic tune up, change fuel pump, fuel injectors, iacv, map sensor, check my timing n it is TDC, check my compression and it passes. With all tat was done, it still sputtering. What can it be? For got to mention, on my forth spark plug seem to have no spark.

Car? ECU? Mods?

No spark = no run

Need to fix why the 4th spark plug isn't getting spark. THAT is your stuttering problem. You are only running off 3 cylinders.

All those mods and you haven't opened up the distributor for inspection?

Sounds like you solved your own mystery....

I did open up the distributor and everything seem fine. I ma try to swap out the ecu and see if it makes any different. I will probably pull out my friend working distributor and see if any of these will fix my problem.
