Engine Performance problem
2001 Chevy S-10 6 cyl Four Wheel Drive Automatic 98000 miles
When the truck sits for more than 6 hours it is hard to start. I.E turns over fine, maybe 1 or 2 cylinders hit and it shutters and sputters. I have tried various routines to start it. Turning the ignition on and off 3 times than to crank on the 4th seems to work 90% of the time on the first start. Fuel pressure 62. When started it drops to 55. I have replaced the dist cap, plugs and wires as well as the fuel filter. Bleed down over night starts at 62 and ends up between 50 and 45 over 3 different test. I am at my wits end here. Thank you for your time. On a side note. When I accelerate with 3/4 throttle it does fine. If I put the pedal to the floor it accelerates but very poorly i.E. It revs VERY slowly and does not down shift until almost redline. I guess it could be compared to hauling a large trailer.
have the same problem?
