Need Tech Help - Test Driving Tomorrow!

Recommended Posts

This is a 94 'Vert that I am going to look at tomorrow.

 

Has 89900 miles

Needs 2 tires

Gas gauge and speedometer dont work

Has idle issue think mass air flow or ecu not sure

Has new brakes

Leather great condition top good condition

 

I spoke with the owner and she said the erratic idle goes away once it's in gear and during driving - it only occurs at start-up. Her father is a mechanic and said a simple computer from the junkyard would fix the gauges and the idle issue would require possible a mass airflow and some other sensor.

 

Does this sound reasonable, or are these major issues with these cars?

Thanks,

Greg Davis

If the car in question is a DOHC car, then most likely the fluctuating idle is a result of a bad lower intake gasket. It is common on these cars, and manifests itself mostly upon startup when the engine is cold. Replacement requires removal of upper intake, fuel rail and injectors, and lower intake manifold.

fuel guage is in no way connected to PCM... that's a bad cluster or fuel level sender.... or a wiring issue.

 

speedo.... bad cluster, bad VSS, bad PCM, bad MEMCAL, bad wiring. that's about it. does the odometer work?

Not sure as I haven't seen the car yet.

If it is a bad cluster, what do they typically cost?
