I just put a motor in my car after replacing the timing belt components, water pump, gaskets, seals, etc. It won't idle. And if you gently tap the gas pedal it will rev much higher than it should. And sometimes it revs pretty high when I don't even hit the gas at all. It backfires and smells strongly of gas. There is some smoke but some of that might be because the engine was just assembled and hasn't ran in a few years. I had the car running fine a couple of months ago with another engine, so I know that most of the electronics work. The car is mostly stock.
I haven't had time to do a boost leak test or a compression test yet. The car is 1-1/2 hours away so its tough.
The ECU is not throwing any diagnostic codes. I have not tried another ECU yet.
I have tried two CAS's and they are not 180 off.
Throttle cable is fine.
My spark plugs are properly gapped and the wires are good and installed in the correct order.
Base timing hasn't been set, but fiddling with the CAS doesn't seem to affect how it runs.
I would think that the obvious sensor/electrical issues would throw a CEL. Or I could have bad grounds?
Seems like an air metering or ignition problem. Any ideas?
