Re: Maybe Fuel Problem? f150 4.9L FI 1990
I got a fuel pressure gauge and connected it. The pressure was plenty high. Apparently, the fuel pump is OK. (At least that part it done.) When I started the engine, this time the engine ran better. But the idle was very high, and I tried to lower it by backing off on a screw that goes vertically and the bottom of which limits the turning of a shaft of the throttle.
But I didn't have a battery jump available, and couldn't restart the engine after I turned it off.
When I start it cold, it's hard to start, and the idle position of the throttle isn't high enough to keep the engine running. But then after it warms a bit, the engine runs way too fast at idle. It seems there is something wrong here.
So I guess the problem now is to get it to consistently run well. And I need to do something to make it run at the proper idle speed.
