Question about 1989 GMC K1500
When driving home this morning, the oil pressure gauge and engine started revving at idol and were very unresponsive to the gas pedal. If I floored it, the engine would slowly increase speed up to 40. Any ideas what the problem is?
Sound like a blocked catylitic convertor, remove down pipe on exhaust and drive to confirm, also check fuel preasure regulator and delivery preasure
