So i have a 1989 VW cabriolet that i bought 6 months ago and did a basic tune up because it ran so terribly.
Did cap rotor and wires with in this year.
Oil change fuel filter etc.
Ran ok but had stunbling issues.
Guy who was a CIS "expert" tuned some things.
Passed emissions and went ok but needed CO adjustment but couldnt find a long allen t at the time.
Got that running nearly perfect and it picked up amazing for half a day (wasnt running lean anymore)
All the sudden it misfired for a couple seconds after restarting so figured was rich (yes i know i should be adjusting co in accordinance through test port and not ear) so turned it counterclickwise a 1/4 turn and misfire tapered.
Then ran good till got home and idled for 5 minutes and nor have a constant misfire like when i got water in my mk3 cap driving in a puddle.
Gone through it all and cant figure it out.
Thought i messed up my distributor adjusting it so through a refurb with no luck albeit does run better with most all parts new and no vacuum leaks now, but still a misfire.
Down to 2 last things to test or try and thats the coil or coil pickup.
My question is whats the likelihood that my coil is not completely failed and passes the tests but have a misfire? Same with the coil pick up in the distributor.
Oh and replaced a bad fuel injection relay since it was badly corroded... idk how the car ran with out it? And literally with it unplugged so am wondering if one of my fuel pumps are bad. Also havent dropped the tank yet.
Im going insane here and luckily passed emissions before this and registered it
