Truck status. ! 87 4x4 ranger 2.9. Work preformed I know of. Top end gaskets all replaced (prev owner) New gas tank (prev owner) He also stated the plugs wire and oil had been changed in the not distant past. I belive the truck sat a few months due to the oil pump being out so he parked it.. I purchased for 500 and had it towed to the house and replaced the oil pump as well as another oil/filter change. The truck then would run great untill warm about 30 min or one trip to my gate and back it will start loosing RPMs 4 or 5 grand is about all i will push it when idleing when i first start the trip the truck will run fine i will shift at about 3 or 4 grand by the time oim on the way back all the RPMs i can pull are 2 grand in any gear and neut there for i have to shift at 2 to keep gaining speed but on hills ect im dead in the water creeping at 2 grand in 1st or to the point it will no longer pull at all.
I have been searching fourms and came across this one http://www.therangerstation.com/forums/showthread.php?t=74056
and follwed his fix replaced the MAP sensor i continued to have the same problem with the cats getting hot so i grabed the saw zaw and off they came i still have the RPM loss with no cats. I pulled the O2 sensor last night same thing this morning. I am going to check the enigne coolant sensor and thermastat here in a bit. Any other help info on this would be help full. I also thought i may have a cracked head or gastek as well due to white smoke coming from oil cap and PVC valve area and kinda sweet smell as well but i accidently left my overflow take unhooked lost alot of fluid added some water to keep test driving and it was drove like that twice a day for prob like 20 30 mins till i loose RPMs and it no longer can get me home lol. Last night while thinking about the head i went and drained the rad fluid to see if i have lost in in those days roughly 4 hrs driving combined and there was close or no fluid loss. Can i assume i am ok or atleast not in that bad of shape in that area. (also the tac gets jumpy/erratic at times while running ok )
