90 240 Wagon, auto, with 200k
Started on first crank all the time.
Nov 06 FPR started to go, replaced with new in Dec 07.
March 07 Started to run poorly, no stalls, shakey at lights and stops
while in drive .
Checked for vac leaks , none. Check hoses and Flame trap, all clear.
Replace injector seals, very small running improvement, but starting
becomes worse.
You could smell the fuel in the exhaust.
May 07 Raplaced AMM with used one 007 model.
Runs great, but idle is high. If I take my foot off throttle on level
road car will reach 20mph
and shift into second without any pedal. It also will not coast when
pedal is released at higher
Rates of speed, 60, 65, 70mph. The rpm's hunt high and low almost
pulse like.
And it is still hard to start, but with much less fuel odor in
exhaust.
I'm leaning towards injector problems. Poss O2 sensor.
Going to tune it up and see what that does.
Any ideas.

007 is the wrong air mass meter for a '90. You need one ending in 016.
