I am just about to start the reassembly on my engine and tranny which I have rebuilt and was looking at the 25 year old parts on the CIS. The car ran fairly well before the teardown for broken headstuds (100k miles) but at constant throttle between 2500-3000 RPM the car would surge up a down within a narrow band like being unsteady on the gas pedal.

My question, while everything is out still is there some more extensive maintenance on the fuel system that I should perform? eg how long do injectors last ? can they be sent out for blueprinting and cleaning? Or do they just get replaced? The injection lines are very stiff but don't seem to be cracking. I see they are NLA on the PP Website.

I've done the basics like soft fuel lines and filter, air box pop off valve but haven't touched the accumulator.

Any good sources for CIS R&R out there?

Thanks Jim
