Hi all. New to the boards. Just purchased a 1986 2wd ranger with the 2.9 in it. Everything was running fine at first since I only took short trips and it was cooler out ( you know like 50 degrees here in florida! LOL) well the other day i had it out in the warmer parts of the day and she started bucking and hesitating and then stalling. Then again the other day almost causing a major accident on a bridge! So now it is in my garage and I am working on finding the gremlin inside. Here is what I know or have done thus far:
-Cleaned intake, all sensors affiliated, throttle body
-Cleaned out EGR. It was VERY gummed up. So bad I had to force a screwdriver through the gunk in the tube leading to the intake!
-did a complete coolant flush. The rad was soo clogged that nothing came out when I pulled the drain plug
-I knocked out the guts of the cats.. Thought they might have been stuffed up but hasnt changed anything.
-The whole fuel system was redone by the PO at Pepboys to the tune of $500. From the paperwork it looks like the did both pumps, filter, dropped and cleaned tank, etc. So I dont think it has anything to do with fuel.. But who knows!
Here is what happens right now. If I fire it up it will run awesome and strong for about 15 min. The temp gauge will get up to a little under half way and then eventually it will start idleing rough and will stall out. Once stalled it will not start again untill cooled. I tried unplugging the O2 sensor just to try and no change happened. I also relocated the TFI to a heatsink away from the back of the motor. This seemed to buy me maybe 5 more min of running but it still stalled. I am on one hell of a budget and cant start throwing tons of stuff at the truck. Im thinking of replacing the TFI since all the things I have read on here point to that causing my exact problems. The plugs, wires, and cap/rotor are all newer from the PO. Also I pulled all the plugs and the only thing I can notice is some white on the tips but nothing bad.
Any help or tips would be appreciated. I really need to get this on the road so I can get back/forth to work when the bank takes my other car
