So in order to proceed you will need to test for codes you wont hurt anything on the system. Then report the code to me. Because there are other components on the throttle body with similar colored wires, I need to know where this component with the clip is located. On the throttle body with the air breather cover removed and standing in front of the car; looking at it from above, the Temp. Sensor would be in the rear of the throttle body with the wires plugging into it from the driver side. Are we talking about the same component? If not please state the exact location.

| I have to work tomorrow and it is to late now so call me tomorrow any time, then we will set up a time to go over it in depth, after work. It is very difficult if not imposable to diagnose cars in a forum. | |
I recently purchased a 1989 metro, it runs fine...sputters a little at takeoff sometimes but idles high, i've read posts about the TPS throttle position sensor and wonder if that is the usual suspect, i have only been getting about 34mpg combined...is this low? the territory i drive is fairly undulating and requires some downshifting at freeway speeds....any help would be appreciated...

Replying to: latchitup (Apr 07, 2009 3:59 pm) To know what your gas mileage should be and to help diagnose it is need to know, how many cylinders, and dose it have stick shift, with or without AC. The spit and sputter can be caused by a TBS, but not the high idle. A high idle is usually caused by a vacuum leek; this is what I would be looking for first; most likely there is too much air coming in from somewhere! It could also cause that spit and sputter, it would also cause a lot of extra gas consumption. Many things can be a cause of to much air; sticking Throttle bodies, a bad PCV valve, a blown head gasket, (Yes! with out having any other symptoms of a blown head gasket) As in! Oil in the water; water in the oil; water coming out the exhaust pipe, or flames shooting out of the head gasket, and or over heat problems. It could have a bad intake gasket, bad idle control valve, a bad A/C idle control motor that’s sticking, some one could have adjusted the factory set idle to compensate for a primary problem in the past, there could be carbon built up around the throttle body, the Idle control valve could be sticking from carbon build, or it could be bad, this would be a good possibility. All of these things are possible and must be part of the process of elimination when diagnosing. First closely listen with your ear for an air leek while the engine is idling; If you don’t here one, then replace the PCV valve, if the trouble is still there do a vacuum test with the idle as low as specified, if the vacuum is still low find the leak it will becoming from somewhere. The 1989 GEO metro 3 Cyl. 5spd with a full tank of gas with no passengers on a flat road at 55 MPH will produce over 60 MPG. City driving could give you up to 47 MPG. If you are equipped with an automatic Trans you will never produce that much efficiency. I hope that I have helped you in some way, it is very difficult to diagnose on line, if not impossible at times
