Won't run after 2 month rest	Sign In

I really could use some advice. I have a 97 Subaru legacy 2.2l. It sat without starting for about 2 months while I replaced a control arm and brakes. It ran great when I drove it 2 mo ago but now it will barely start. It will only run if I hold the gas pedal just above idle and keep the RPM below 1000. Above 1000 the engine backfires and is real rough, release the pedal and it dies. The exhaust system will get red hot after a couple minutes running. I removed the front cat. to make sure the exhaust isn't clogged. There is nothing blocking the intake. I drained the gas and put new in, no help. I removed a spark plug, it was covered in gasoline. The check engine light is out while its running. Maybe the computer is screwed up because the batt was dead?
Any thoughts would be much appreciated.

Were all the plugs wet with fuel or just the one?
You may have a fuel injector stuck open and dumping fuel into the cylinder?
Just guessing?

Thanks Dan,
Stuck injector sounds plausible. I took 2 spark plugs out. I'll look at the others.

Just to add another idea. If the fuel system checks out ok, check the ignition system. If you have no spark on one or more cylinders, the fuel will be ignited in the converter causing it to overheat and glow red also.

While I was checking the timing and spark, I remembered that disconnecting the batt will reset the computer. I did that and it started up and runs great now!!
