Wur '80 sc
The car has rough idle, both cold and hot, with no power on accelleration with backfire/popping if too much pedal is used. The wur is only 10 ohms.
Any thoughts? Thanks. |

Major vacuum leak or crossed plug wires is my thought

Was running fine so it couldn't be plug wires. I had considered a vacuum leak but if it was would the rpm still drop when removing the oil filler cap?
Thanks for the responses. |

Fuel pressures......
Quote:
David, Have you checked your fuel pressures (control and system)? If the RPM drops 200 or more after you removed the oil cap, it's an indication that you didn't have a significant air/vacuum leak to effect fuel mixture. Have you checked your ignition timing and spark? Keep us posted. Tony Last edited by boyt911sc; 07-06-2012 at 01:22 PM.. |

The fuel filter is about 2 years old but might have only had 2 or 3 tanks of gas through it. I have an extra so I'll give it a try.
