I have an weak injector, hard cold start. I am going to pull all of them and clean the spool valve, and replace all of the o rings.

My question is, How do I clean the spool valve bore and can I clean the tips?

Thanks!!

 

I wouldn't Play with Tips at All

Find anything Suspect there replace inject

Theres a thread in tech folder about inject spool valves and IIRC there was some cleaning recommendations

When I do mine I Hope to find a Cleaner to Clean spool valves and Nothing Abrasive or to intense maybe a Scour Pad or something

I was going to clean the valves with an ultrasonic cleaner then polish them up, It was the bore that the valve went into that I was wondering about.
