Guest grim83 Posted October 13, 2010 Report Share Posted October 13, 2010 Hey guys im looking at buying a 75 c10 and i found something a little questionable. I didnt get to get to in depth with the first inspection but i did find that it has straight 6 with a 3 speed tranny. i cranked the truck and was amazed at how smooth sounding and quiet the engine was compared to nearly every other car ive been around, even without a muffler the thing is very quiet. The only problem i had was that it seemed to idle up a little bit and then started to drop like it was going to stall any ideas as to what might be wrong (i was able to keep it from stalling by reving it a little).

David78 Posted October 13, 2010 Report Share Posted October 13, 2010 Maybe try adjusting the idler screw, Typical old trucks like to rev around 750-950 or so, Bad timing can cause low revving, Bad gas etc. Quote ...............................____ ...............__________|___\____ ..;.;;.:;:;.,;.|__(O)____|____/_(O) 1978 F-150 Ranger Lariat 2 Sets of Sound-stream Components Sony Head-unit DDM Tuning 8000k's Euro Headlights (Projectors Soon) Green Led Wheel Wells Dark Red Tails Tint Link to comment Share on other sites More sharing options...
