1987 Wagoneer Limited 4x4 Fuel Injected Inline Six Cylinder
 

I recently bought my Wagoneer. It ran great, but lately has went down
hill. About a week ago my Wagoneer would not go over thirty five
without cutting out. I would have to let up on the accelerator until it
would quit cutting out. It was not a good feeling being in traffic when
this started occuring. The problem has only gotten worse. I was driving
home from work when the motor completely died. My Wagoneer would start
up again but would not remain running for very long. I had a heck of a
time getting it home. I could only go about five miles an hour and even
then it would cut out and I would have to pull over. The next day I
replaced the fuel filter, plugs, plug wires, distributor cap, rotor and
air filter. It has done little good. It will start up but will not
remain running for very long. Any help and/or suggestions would be
greatly appreciated!!!

That's old enough the fuel pump may be giving out. Least wise that's how
it acted when my old C-10 chevy burned out the pump lobe.

A fuel pressure gauge should be your next test. IIRC 3-5 psi was normal
for a carb.

When that happened to our 88, it was a rotted ground strap from the rear
of the engine to the firewall. I would start there.

Re: 1987 Wagoneer Limited 4x4 Fuel Injected Inline Six Cylinder
 

a 4.0 engine with the Renix system huh?
Maybe a CPS that is going out or a camsensor going out
Or an ign coil that is weak
Check the TPS
Check the MAP sensor and vacuum hose going to it.
****** Probably the EGR sticking open.******
Might be a problem with the CTS or the 02 sensor
Check the fuel pressure too, maybe the hose on the fuel pump is leaking
inside of the tank.
Check the oil level and condition to make sure it is not too full and smells
like gas.

And the simplest thing is BAD GAS!

good luck!
