1990 Ford Tempo (4 cylinder)
2.3 L - manual transmission
VIN # 1FABP35XILK234531
Odometer – 245 270 km
Vehicle in trouble Sept. 6, 2012
Please help; I have owned this car since 1992 and have good records of the work done on the car. It is past the point where I want to spend a lot of money on repairs. I have access to a 1990 tempo parts car, if swapping a part could prove useful in determining the problem.
The problem I am experiencing is intermittent and is unpredictable as to when it acts up. I had originally thought that the symptoms are only exhibited when the engine heats up and generally when I am shifting gears or pressing on the gas pedal to speed up. But this does not hold true in all cases.
Basically the symptoms are a sudden loss of power (not a gradual slowing of the vehicle) that feels like the lurching one would experience if one was just learning to drive a standard transmission – ie: jack-rabbiting.
It doesn’t seem to be transmission related when the symptoms show up; as I can see the RPM gauge drop 1000 RPM when I rev the engine in neutral.
Trouble codes that are shown by the computer are;
“0” or (Key On Engine Off ) KOEO codes;
11 - system Ok
“C”(continuous memory) codes;
14 - Ignition profile pickup is eratic
18 - “SPOUT” circuit open
[SPark OUTput from PCM to TFI module(on distributor) is not closing?]
“R”(engine running) codes;
21 - coolant temperature is out of specified range
52 - power steering pressure switch is out of specified range
I have a small coolant leak as I have noticed some dry coolant on the engine (appears under the Air filter and toward the firewall). This probably accounts for the code 21 above. I suspect this is unrelated to the erratic idle (lurching) issue, but I am not a mechanic.
If anyone has experienced these symptoms or knows what this problem probably is, I would appreciate communicating with them.
have the same problem?
