I have a 5 cylinder V6
The 89 Green sedan when purchased almost a year ago now had a bad miss when I got it. Fiddled here and there with new plugs, leads and some injector cleaner which made it run alot better. But it still has a miss in it.
Car has plenty of power. I'm thinking it's not a burnt valve as it revs nice and takes off no problem (thanks to a greenfoam tune)
I've got the econnomy down to the 12's (from 18's) L/100kms. O2 and temp sensor fixed most of that.
When you bring the idle up to 1500 the miss is intermittent. (burnt valve would be consistant I would think)
I thought it may have been No 5 as when I took the injector plug off it had the least effect. BUT on close inspectoion of the lead it was not even on the coil plug properly - pulled back into the rubber boot. The top of the coil pin was a bit corroded. Cleaned that up and new plug lead for No 5. Re tested the injector plugs off again and No 5 had the least effect again. Changed plug again - but no change. When I pull the injector plugs off all the others the engine almost stalls every time.
I swapped over coils (has the 3 small units) to see if I could move the problem - but no. Could not really tell.
The harmonic balancer looks new. Can the CAS cause a miss? The car dosent stall at all.
It looks like it's a recon engine as it has tags on the rocker covers to that effect. Car has done well over 350,000 I'd say.
