Hey,

I just finsh installing the single turbo to my car. This has been an on going project for me.

I have a problem with my idle and part throttle. The only changed that I've made to my car from the stock twins to single are: upgraded RC 1300cc injectors, change setting on my PFC for the 1300s, got rid all but four vacume lines, stock ports, intercooler pipe change, and I blocked off all emission related items. No, I have not purchase the fuel pump nor the FPR.

The problem with my car is that it will not idle smoothly. The idle is very rough, kinda like a running a big as cam on a boinger. I don't think all the plugs are firing. The car runs like its missing and is lacking powers. You can smell the alot of raw fuel come out of the tail pipe.

I have double check the spark plugs, plug wire connections, and the coil harness. Everything seems to be okey. What should I be looking out for? Is it ignition related or something else?

Check for spark. The plugs and wiring to the plugs and coils may be fine, but it doesn't show you the coil condition (drivers).

Use a Volt meter with the impedance measurement selected and Ohm out the coils to see if the coils are fine.

My car ran the same way and it was intermittent (normal some of the time and then all of a sudden, it was like running on one rotor and wreaking fuel, then kick back in after some random time interval).
It turned out to be the MSD 6A. I checked everything, but saved the MSD/Coils for last since I wanted to make sure my wiring and so forth were not at fault. I just bypassed the MSD and my car hasn't seen the intermittent problem since 1 month ago.

Good luck!

Thanks for the advice. It turns out that my leading coil are bad. The manual spec is anything under 1.00 Ohm. It read 0.00 Ohm which is a short reading. The trailing coils read 0.03 Ohm. This must mean that the leading coil are dead right?
Thanks,Jay
