Good day all,
I did a bit of searching around and seem to think this is either a MAF or TPS issue.
The deal is that upon startup, sometimes, more often when cold, the subie pukes tons of black smoke (fuel over use). Turn the car off, turn it back on again and it may.........or may not be fine. Usually after a few shots at this we're good to go.
Some days it's just fine.
Have poured tons of cleaners down the throttle body in the past, new plugs, wires etc, but if it runs well sometimes, should be none of the replacement parts correct?
In any event, please point a guy in the right direction of "first this, then this" type troubleshooting. I'm counting on experience to save me some hours here.
Additional info, the car "grew up" on the east coast and now resides in northern california. 212K miles, new cats last year to pass smog, manual, 22 or so MPG. Used for towing scrap metal (1000-1300#) net weight (maybe an additional 300# trailer) a couple days a week for 40 miles.
Fresh timing belt etc.
Thanks in advance,
Nick
