Started up fine, then started to fluctuate between 950-2000 in neutral. Drives fine, until idleing @ stops, then goes nuts!!
It revs up & down in like 2 second intervals. Things I will check tomorrow-- Dizzy, plugs & wires. Thinking about spraying the throttle body with carb cleaner. Check vacuum lines. Any help, tips or tricks GREATLY APPRECIATED!! Thanks!!!! |

Replaced all vac lines.
Start up idle is 1800, warmed up idle is 1400. Pulled the fuses for ECU & put them back in 15 mins later. Pulled the 1 in the engine bay & the 1 in the car. Tach still has slow response when slowing down // gear changing. What next?? I can't thank you guys enough for the help!! |
