Pathfinder-jay Posted March 24, 2006 Share Posted March 24, 2006 ok I got my truck back again today, all gaskets changed in the motor. Now it doesnt hop anymore since the vacuum is tight in... but for some reason my rpm is bouncing around...dunno why Link to comment Share on other sites More sharing options...
Mr. Pickles Posted March 24, 2006 Share Posted March 24, 2006 all gaskets changed in the motor Ummmm... I doubt it. That would be a big labor bill to randomly change gaskets. Link to comment Share on other sites More sharing options...
94extreme Posted March 24, 2006 Share Posted March 24, 2006 sometimes the guages do go out. check the rpms with another meter and see if is all ok. Link to comment Share on other sites More sharing options...
Pathfinder-jay Posted March 24, 2006 Author Share Posted March 24, 2006 Its not the gauges because you can actually hear the motor going up and down and you can feel it. The gauges are new aswell.... And yes changing gaskets does cost alot of money if you do it at a garage since its alot of labour...time consuming. But the weather over here will not allow me to work on my own truck... I even replaced my whole air intake systeme with 02 sensor to see if it was that. IM bringing the truck in to reset the computer this morning. See how that goes.

90seven Posted March 24, 2006 Share Posted March 24, 2006 Can't you just leave the battery unpluged for a minute or two to reset? Link to comment Share on other sites More sharing options...
unccpathfinder Posted March 24, 2006 Share Posted March 24, 2006 is this all the time or before it warms up i know my truck bounces up and down when its almost warm (the 87) and will flatten out once its warmed up Link to comment Share on other sites More sharing options...

94extreme Posted March 24, 2006 Share Posted March 24, 2006 Can't you just leave the battery unpluged for a minute or two to reset? yeah or turn the screw on ecu to clear. no need to pay someone to do that man. Link to comment Share on other sites More sharing options...
Pathfinder-jay Posted March 25, 2006 Author Share Posted March 25, 2006 Ok i fixed it, i took my multimeter and messed around with the wires near the ecu computer... its busted, always constant power. I replaced the ECU with the other one in my 92 pathy and it fixed the problem, my mechanic did it all for free, i went to pay and he said dont worry bout it...dads old friend and my first car... he seems to love my truck and the fact that i wont give up on it lol. I did most of the work myself in the garage anyhow... rewired, put plastic conduit to protect wires, and added a new ground... old one was @!*%. Re-wired my fuel pump aswell.

Harbinger Posted March 25, 2006 Share Posted March 25, 2006 What do you mean by always had constant power? Seems to me like at least one of the ECU wires would always be active :confused: Link to comment Share on other sites More sharing options...
Pathfinder-jay Posted March 25, 2006 Author Share Posted March 25, 2006 yes but it was not grounded.... and someone rewired it so that an extra wire ran with a hot... hard to explain youd have to see... anyhow shes all jgood now Link to comment Share on other sites More sharing options...
