Engine 2001 Gt 4.6 Idle Rough And Will Not Stay Running

RlovellGT · Feb 18, 2015

The injector under the schrader valve is pouring fuel out, while the others are spurting fuel..
Should it be pouring out when starting or what?

I'm actually considering just replacing motor. I know that might sounds like a crazy idea but I'm afraid if I get this issue, whatever it is, something bigger might be wrong..

I'm just so frustrated, and could end up spending a lot more than a motor just troubleshooting "possible fixes"

You mean the spray pattern on the injectors? They all should be spraying the same in. Not one cylinder should be getting more or less fuel then the others.

You said you had pressure there earlier....between 40-50psi, then it would drop down. Is that not the case anymore? You should get a cheap, mechanical fuel pressure gauge, remove the schrader valve, and thread the gauge on. If you are seeing pressure, you are good. If there is no pressure, that is a problem.

Get some electrical parts cleaner from the auto store, and clean the MAF. The MAF must be plugged in, and the CAI on for the engine to run correctly.

Any codes? A car running that bad should have something to say.
