i have had a problem w/ my 94 ranger that so far NO ONE has been able to answer. it is a 2wd 2.3 reg. cap 94' ranger. i bought it for $2800. it had 120,000 mileson it. It now has 150,000 miles. it has been a really dependable truck. In 30,000 miles of drive it, i have had to replace a hearter coil, fuel pump, water pump and timing belt. nothing major.i changedeverything myself, i trust on one else! right now it has a recurrent problem, well really two..

right now, after i have drove thetruck around a while, and got the engine warmed up; if i shut the engine off. go in to astore or something, ori can even let if sit for a hour, i go to crank it and it cranks just fine. then the truck runs a little hard, and the voltage gauge goes down. (i thought it might be the alternator, i replace it, and it still does the same thing) during the summer it might do this and shut off (run hard then shut off), but it doesnt shut off all thetime. Usually itruns hard right after cranking, then works back to normal. it is reallyaggrevating.

not only that, it seems to lack power. it is a manual, so i have a little control over it.its really hard to maintain speed up hills in 4th. if i shift down to 3rd, it doesnt really speed up, just revs up and speeds up VERY little. driveing up a hill down the highwayat 65 MPH in 3rd is not good! i shouldnt have to shift down to 3rd just to maintain speed on the highway upa little incline!

ihave put on the following, and nothing has helped:

-high flow MAGNAFLOW catalytic converter
-BOSCH platinum plugs
-New fuel pump
-Replace air filter every 12,000 miles
-new timing belt (changed myself)
-new drive belt
-new alternator
-new battery
-new battery cable terminals

it seems that the first problem is electrical because of the gauge, but im not sure, and as to the power, im really dont know. is there anyone that can help me sove my two problems. the first problem is a major problem that i need fixed and so far ive had no help, can any one help me?

 

I'm not absolutely sure, but could it be a cam position sensor? I think the cam position sensor corrects the timing advance. It may not be picking up the cam. Its just a guess, but maybe it will lead to something. Good luck.
