1998 Tahoe 2 Dr 4WD, 5.7L, 4L60E 150,000 miles
The problem occurs after vehicle is up to operating temperature.
Engine pulses when turn signals are used. (Either signal, including hazards).
When trying to accelerate, RPMs increase but vehicle doesn't accelerate accordingly.
Here's what we've done:
1. Changed shift solenoids and did a filter and fluid change on transmission
(no change)
2. Cleaned EGR (no change)
3. Replaced TPS (seems better for two days, then symptoms returned)
It shifts fine through all the gears. Any ideas?
