1997 Ford Ranger Idle Problems

Mileage 90,000. (Fuel Inj) My Ranger runs fine if I start with a cold engine. Idling is not a problem until the engine is shut off after running for awhile. Then after I restart (while Engine is still warm) ... the truck will not idle. I have to rev up the RPM to keep from stalling at stoplights. This problem will persist until I finally shut it off and let set until the engine is cold. Been looking over manuals and was wondering if it might be the "Idle Air Control Solenoid" or possibly the "Throttle Position Sensor"? Any guidance would be appreciated! - Midwest Ed -

Rule out vacuum leaks first. Then get a code read as it must have something stored. A TPS can cause problems for sure but I don't recall any being highly engine temp sensitive, T

Another thing to check is fuel pressure. If the pressure is too high, you will idle OK cold because your truck needs a richer mixture. When it warms up however, it will be overly rich causing the engine to choke out. Rule fuel pressure out before you get into the computer aspect. Steve

This one has been a little tricky. The Check Engine light never comes on. Will a code still get stored in that scenario? I had the Ford dealer look at it about six months ago when the problem started. Of course by the time they get around to looking at the truck, the engine is cool and it idles great. They we unable to locate any problems. This is a real pain. When sitting at a stoplight I have to drop it in neutral, keep one foot on the break and the other on the gas revving up to about 800. I guess I'll start by looking over the vacuum system for any leaks. Thanks for the feedback. - Midwest Ed -

RE: Fuel Pressure Guage. Looks like they run about $50. Is there a way to test this without buying a guage? Thanks. - Midwest Ed -

Just know MidwestEd that the cost of tools to do this stuff would scare the hair off of most folks! It really is a reason that prices are high. Let's not even get into the cost of a place to do this, the taxes, hazmats, -- it goes on forever. Almost every place around me that has sold out became coffee and donut shops, T

The tool rental program is a great thing for most folks. More and more places are doing it. For fuel pressure on a Ford you might be able to use a tire gauge but it would certainly ruin the gauge, T
