Rich Fuel Mix on B230 Engine 200 1985

posted by  someone claiming to be Ed Wright on  Sat Nov 7 03:54 CST 1998 [RELATED]

I have a 85 245GL with the B230 Engine. It failed the VA emissions inspection due to burning too rich. Had lots of things replaced (Air Mass Meter, all tune-up parts, found a leaky vacuum hose, new catalytic converter (before I realized its electric)).

Found a short in the wiring harness on the firewall (at a grey junction box). Fixed this, but engine is still burning rich (rough start when cold, then a little vavle knocking when hot).

Can anyone tell me if the Air Mass Meter got shorted by these bad wires, or should I look at the ECU???

I got the waiver for the emissions inspection (by spending too much money on repairs), and I don't want to go broke getting this thing to run well again.
