Injector Issue (I Think)

[NoDOHC]

One thing I found is that coolant seal failure-induced hard starting can be greatly diminished by removing the radiator cap right after the car shuts off (get a rag).

The cap can be replaced right after the car has started again.

I found this to work well on my '86 with the original engine in it (I drove it for months with bad coolant seals until I couldn't keep enough coolant in it to keep it from overheating).

If this helps that starting issue, I doubt that it is injectors.

The injectors on my '86 had 200,000 miles, 20+ years and 1 pulsation damper fire on them and did not leak at all.
