Answers :

The engine\012and transmission in this cars drive train are fully\012electronically controlled by a computer called the PCM (Power Train\012Control Module). Whenever a problem like this occurs the computer\012stores a record of the problem (there are of course some exceptions\012to this, like the fuel pump, engine coolant teperature sensor and MAF\012sensor for instance) in the form of a fault code in its memory, to\012read these fault codes you must have the systems memory scanned with\012a special tool. Once the fault code(s) are read you then must perform\012the appropriate diagnostic testing to find and resolve the problem(s)\012DO NOT REPLACE ANY PARTS UNTIL THE DIAGNOSIS & TESTING IS\012COMPLETED.

My speedometer is not reading my speed! My accelaration and the power to go is completely there. If I'm on the freeway or parked, gauge says that I'm still going 25 mph. The gauge does move, but is FAR from accurate. Please help with suggestions to the cause and how to fix. :)

If the odometer is correct, the problem is in the speedometer head. If the odometer is also not accurate, it may be the speed sensor in the transmission. ... 1995 Lexus ES 300

Power seat we just got the van. The drivers seat is power but it won't move. There are some wires laying behind the seat. The seat appears to be wired. We were wondering if those wires could go to the control switch that moves the seat. There doesn't seem to be any power to the control switch but there is power as the power seat is on the sam circuit breaker as the power door locks and they work fine. We would appreciate any help you can offer. Thank You: Confused.

I have a 1986 Dodge mini van 2.6L Mitsubishi Engine Carburetor On a recent long trip after half a days travel, the van began to loose power while going up an incline. The next stop was 25 miles away. When I got on the flat and got the van up to 70 mph it was OK, but when I lost speed due to a hill or traffic and went below 55mph, I lost some power again with some missing. When I returned to 70mph, ok. Also, if I pushed the throttle hard, there was a real loss in power until it got into p

I have a 1999 ford escort LX with a little over 100,000 miles. While driving home from work the engine started "chugging" and losing power to the point that I could barely move. When in neutral the engine ran rough but would rev. When I put it back in gear the car would barely move, the check engine light began flashing and there was a slight burnt smell. The car has no problem starting but I am now afraid to drive it anywhere.

The first place to start a diagnosis on your vehicle is to verify the diagnostic code that is stored in the PCM (powertrain control module, aka computer). If the engine light is on, then the system has detected a fault code with one or m ... 1999 Ford Escort

Speedometer malfunction I have a 1987 Porsche 928 S4 with 89,000 miles. Recently, the speedometer stays at zero even when the car is moving. After a while the speedometer reads correctly but when I slow the needle seems to stick at about 25 mph. Is this a cable problem. If so, how do I replace it? If not, do you have any suggestions. Also, the gas gauge misreads at the same time. Thanks
