hello all...

I have an 87 16 valve with 54,000 miles that recently received some exhaust work. The new system includes all free flow components with Lorinser muffler and no pre-cats. My questions:
1) What tuning changes or adjustments need to be made to best suit the characteristics of the new exhaust system?
2) The car is now having trouble maintaining a smooth idle...is this normal or do i need to change O2 sensor?

Also, I know this is getting long, how often do the following services need to be performed:
-Fuel Injectors Cleaned
-Valve Adjustment

Thanks in Advance

I'm sure that the engine would like a bit more fuel & even timing. Fuel pressure change at the EHA (governor) on the fuel distributor would really help. The system works on a 2-tier fuel pressure system. By lowering the lower chamber pressure the engine will run richer. The computer is constantly changing this pressure.
