I just did a 15k tune-up on my wife's LX because it was mis-firing like crazy at anything over half throttle.

The fuel filter looked like it hadn't been replaced in awhile, so I just went ahead and did plugs, fuel filter, air filter, and an oil change and it was running great again.

I also cleaned the throttle body out a bit and cleaned and re-seated all the connectors ounder the air box because the car had been throing throttle position sensor codes which were bothersome and caused the tranny to shift in a sloppy fashion. The code disappeared after I ran some contact cleaner through both ends of the connector and sprayed some carb cleaner down the throttle body. It hasn't lit up again yet :D

It ran great the whole day, but this morning I couldnt' get it started and had to pull the EFI fuse and crank it for awhile until it started. I had to do the same thing when leaving from work when it had been sitting for ~7 hours.

I pulled the throttle body again tonight and re-seated all the connectors around it and pulled the battery cable to reset the ECU, but I'm afraid it's going to do it again.

I highly doubt I have a leaky injector somewhere. What would cause it to have this damn problem now? I'm figuring I screwed something electronic up or there's something more sinister going on.

Thanks for any advice!

Sure enough, went to go to work this morning and it's flooded out again. The plugs are SOAKED.

What's a good way to test injectors for leakage? It really sounds like that's what it's doing, either that or it's not firing correctly.
