Engine Performance problem
1997 Chevy Astro 6 cyl Two Wheel Drive Automatic 162, 00 miles
1997 Astro Van, been a great vehicle for us, and choose to keep her, as dealer will only offer $500 trade in value. She starts and idles sweet, but once you get her out of the driveway, as the RPM'S increase up to the shift level, engine cuts and shudders mildly until she shifts into the next gear. Same with remaining sequence of shifting. I don't believe it's a transmission problem, just seems the engine is having some type of ignition or fuel delivery issue. Once the engine is hot, all is normal. There's no "check engine" light on either. Symptoms VERY pronounced when engine is cold, but dissipate dramatically once engine is hot. Im thinking fuel injectors right off the bat, but really, I have no idea. Plugs, wires, cap and button all new, new fuel pump also. Don't want to be raked over the coals at a repair shop, and am pretty good mechanic, just want to minimize the pain. Thanks, and great site. Mark in Hiram, Georgia.
have the same problem?
