Hesitation / Bog ??
Quick background: 90 Coupe, Auto, 2.59 gears.
Before reaching normal operating temps, during part throttle acceleration I've noticed a hesitation or bog, for lack of a better term, after the car shifts into 3rd. Usually, this will happen from 36 to 42 mph, at which time it will seem to "catch" and accelerate.
I've ohm'ed the injectors (16.3 - 16.6 cold), reset the TPS from .69 to .54 ( yes, I "know" they weren't adjustable during this time frame
). Pulled the throttle body and cleaned the IAC, etc.
I've tried to work through the FSM troubleshooting guide, but apparently my comprehension isn't too slick
and I haven't had any luck or I've missed something.
It also appears that I have the dreaded Multech injectors but I'm not in the mood to sling money at this car without doing this correctly.
Opinions anyone? Injectors, TPS, IAC, tranny...??? Anyone have something similar to this?
I've learned a lot in the last 8 months from this forum and the archives and hopefully I'll learn more after this.
Thanks
