Need help from pros, 87 ALL STOCK GN 100k miles. Car idles good once it warms up, choppy when cold, car has always ran warm 200-210 according to gauge.New 160 thermo.
Engine cut out at 5k in park, and cuts out at 3500 in gear on jack stands. Sounds like a rev limiter when it cuts out. Blackish blue smoke blows when it hits 3500 rpm in gear. Plugs are black but not wet, car seems to smell rich in garage. I have tried
New plugs/wires/air filter no change, new MAF no change, new coil no change, different stock chip no change, new Walbro 255/hot wire and sender and tank no change.
triple checked vac lines and crank sensor. I have scanmaster all readings below in park. I realize readings are limited but if anyone has a suggestions it appreciated.
At idle At 3000 rpm At 4500
