Please help me...I have a 1993 GMC Jimmy 4.3 W sereis...with 134,000 miles that starts hard and seems to run rich...???
I have had the erg valve removed and cleaned twice...
And replace the plugs and three had a green tinge to them...
Then, the oil got about a quart of gas in it...
now it stinks at idle and I must put it in neutral at a stop or wants to kill...any ideas appreciated...mjohn1@maxminn.com
