here is the problem , my car is a 90 N/A automatic ,
when I WOT the car , it runs fine below 4000rpm , but after 4000rpm
the car is rev super slow , and the car won't go , feel likes you shift to "N"
no matter what gear , it won't rev after 4000rpm, but light throttle can rev
to redline, can anyone help?

Did you check your engine for "error" codes?
If you don't know how, I advise you look at the TSRM (repair manual)

today I drive my car around , right now my car won't go after 4000rpm
no matter light throttle or WOT , my engine light doesn't on , but my coolant light is on ,
I think the plug of the sensor is broke , will this cause this problem?
and I will try to check the error code but the I don't have the "SST" thing , is it just a jumper wire or what ?
thanks
