My check engine light comes on only when I accelerate. It goes off when I let up on the gas or just cruising. As soon as I step on the gas it goes on. Anyone have this same problem??
Well I pulled the codes here they are: 31 and 63. What do you guys think???90silverstang said:My check engine light comes on only when I accelerate. It goes off when I let up on the gas or just cruising. As soon as I step on the gas it goes on. Anyone have this same problem??
Thanks, I will check TPS tomorrowIdwitheld-1` said:31 = EVP OR PFE circuit belowminimum voltage
63 = TP circuit below minimum voltage
EVP = EGR valve position...check connector, wiring, clean pintle tip.
TP = throttle position...check connector, wiring, possible dead spot in pot.
Hope this helps.
I purchased a code reader from Walmart for $25.00. The brand name is Innova Model 3143. Hope this helps.MSM0075 said:Just curious, What device/method did you use to run the codes? I used a OTC Scanner on my '93 beacuse I thought the TPS was bad and it pulled a lil different codes everytime I scaned.
Thanks for info., Itwas a bad TPS. It had a dead spot in it, also replaced the egr sensor it was intermittent also. Thanks again.Idwitheld-1` said:31 = EVP OR PFE circuit belowminimum voltage
