hello, I have a 95 astro (W) which runs rich. I can smell gas out of
the exhaust.

i have spend some money on tuneup (spark plugs, wires, distributor cap,
air filter,pcv valve). I changes, spider injector because previous one
as leaking and flooding engine.  Can you suggest me what else i should
check/replace.

I plan to see what the oxygen sensor says this weekend.

What about temperature sensor, or map sensor? doyou tink they might be
related somehow.

It doesnot smell all the time. but once a while, something intermitted.
The car runs smooth, with lots of power.
