Question about 1994 Chevrolet Astro
This vehicle has sat for almost two years. The current issue is the same issue that led me to lean on my sedan instead of my van (oh yeah, and the fuel prices.)
When I put it aside 2 years ago, we had a code 32.
Replaced EGR Valve yesterday. No more code 32.
Code 43 comes up about 30 seconds after starting the vehicle.
Vehicle runs excellent at speed, idles rough almost to the point of stalling when stopping.
Alternator replaced this morning.
Spark Control Module (underneath distributor) replaced.
Vehicle exhibits same symptoms.
When I put my foot into it, the van will take me anywhere I want to go. It idles extremely rough and almost stalls at stops.
I'm dying for a suggestion.
I would replace the Fuel Filter and Run a Can of B12 Chemtool with a Full tank of Fuel before you start Draining the Fuel out of the Tank.

Code 43, i would expect with running rough but that's not the cause , its a result ,if the system detects noise (knock) it will try to compensate by retarding the timing to save the motor , built in self preservation , i hope your not running on 2 year old gas , i'd be amazed its even running at all , gas varnishes up bad enough in 6 months to 1 year , i suggest getting some fuel additive in there to stabilize and clean the fuel system , or have it drained and start over with fresh gas and go from there . cheers .
