Re: 94 Blazer rough idle~stalling~low power HELP!
Little background on car. Car has 125,000 miles on it. Rebuilt engine was put in at 78,000. That is when I got it from my mother (who bought a new car when engine went in this one). Since that time I have replaced... battery, water pump, brakes, exhaust, gas tank, fuel pump/sender, shocks, plugs and wires, pcv valve, coil, starter, air filter and I am sure I am forgetting something. A 'free' car is NEVER free. lol
Ok, this problem started a year and half ago. It was winter and it would not act up until the car had gone about 30 miles or so and was well warmed up. (20 degree weather or less). Almost felt as if it was building up pressure and would sort of surge when I let off the gas. Oil pressure drops and rises with this. I had new wires, plugs, fuel filter, oil change done to see if this cleared it up. As spring warmed up it did it more often, the warmer the day the more bitchy she is. When we changed the muffler and gave the catalytic converter a good rapping it seemed to run better for awhile. Checked the ERG valve and intake, cleaned them well. No change. Changed coil, nope! The longer I run the car the worse it gets. Really dislikes hot weather (been in the 90's for 3 days now). You can smell that it is running rich and also the sulfur smell from the converter. Will restart right after it quits and sometimes even runs decent for a short while. Some days are so bad I have to two foot it at stop signs. Fine while accellarating but as soon as you let up at anything under 60mph it starts it sh#t.
So there you have it. Still think the lake is my best option as I am out of patience and money. lol
