Rough Idle, RPM's don't match what engine actually running

[85HotAirGN]

hi guys!
well I got the '85 running. I put in a new fuel filter and now the car has a terribly rough idle. I'm getting any where from 8-10 ohms resistance through the plug wires so they are getting replaced tommorow. It falls on it's face threw throttling and isn't boosting worth a flip.

Another thing is that the digital RPM gauge in the dash is reading 2900RPMs and the engine can't be turning any more than 800-1000RPMs. Anyone have any ideas on what to check to solve this problem.

I know the MAF sensor could cause some of the above problems, need more ideas, anything would be helpful. The car only has 45K miles on it and has sat for over a year.


THANKS fellas, any help id greatly appreciated!!!!

Respectfully,
Justin

The dash tach is crap. As for your other problems have you verified your sensors and maybe done the spring cleaning? If not follow the link and do it. Good luck. james
