1990 spider - after an engine compartment rinse at the car wash, now acts as if it has a rev limiter set at 3500 rpm. Runs great everywhere under that -- good idle, good power, pulls smooth... until 3500 rpm.

Any idea what may be wet/loose/dead? (already swapped plug wires)

thanks,
wm.

I'll start.

Check that all grounds are clean and secure.

Does the 1990 (Motronic) have an AFM (Air Flow Meter) like the L-jet Spiders? If so, check if the harness connector is loose, wet, etc. Maybe also make sure the flap inside the AFM moves smoothly throughout its range of motion.

Same for the TPS (Throttle Position Switch).

bingo

Yes, the Motronic does have the AFM like the L-Jet. I blew out the connectors in both the AFM and the TPS, and bingo, problem solved (some offending water, apparently).

thanks for the help,
wm.
