93 engine light

[PimpinProbeGT93]

this is the problem when i dive down the road and hold the car at a constant speed after like 5min the check engine light comes on but it will go off when i turn the car off then back on agian and if i put the car in nutral (i got a 5 speed) and then put it back in to gear and go then the engine light stayes off i think that is might be my o2 sensor but i just wanted to her what ya'll had to say bout it

Probe your pcm and see what code you are getting. more than likely o2 but you never know.

Sorry PCM (the powertrain control module) The connector is located under the hood by the battery. You will bridge the sti and grnd terminals then turn your key to on not run and count the flashes. long flashs are the first digit of the code fast flashes are the second digit. keep track because you may get multiple codes. The VAF is the volume airflow sensor or maf mass airflow sensor. If you need any help locating the terminals do a search or let me know I will forwaard on some pics.
