Hey gang, thanks in advance for taking the time to check look into my issues, and I'm sorry this is so long. I have searched the forums and can't find anything yet.
As my signature says, I have an '87 Samurai running a '92 8-valve 1.6L TBI Tracker engine; 92,500 miles. It's been running great, until a capacitor in the ECM exploded and took out the circuit board. I replaced the ECM and the engine started. Before driving it, I decided to do a tune up. New plugs, wires, cap, rotor, air filter, and TIMING BELT.
It's now running odd. Everything seems normal over 3,000 RPM. Below that, there's no power. The feeling is as if it's running on half of the cylinders, even though that's not the case.
The other symptom is hard starts. When it's cold, it will start, but idles really rough. The idle is low, under 500 RPM, and I have to S L O W L Y depress the gas pedal to get the engine up to speed.
Check engine light functions when key on-engine off. Not on when running, no codes stored. EGR is not clogged (but I cleaned it anyway). Timing is set 10* (a little higher than the 8* recommendation, but that's needed for our altitude here). I set the timing with the diagnostic connector jumped.
Some background: I did the engine swap. I've put about 8,000 miles on it since the swap. I swapped EVERYTHING from the Tracer engine-wise. All fo the emissions stuff is there. It's still running the factory Tracker air cleaner. Vapor canister. Both the donor and Samurai were a/c cars, so I figured "what the heck", and it has a/c. I had to replace the Idle Air solenoid after the swap, so 8,000 miles ago.
I've read a few posts on the timing check that requires removing all plugs and F1 fuse and using a compression gauge. This confuses me, so if anyone has a better explanation of this, that'd be great.
Thanks again everyone, and I'm sorry this is so long.
