Hello all~
I have a 1994 XL, 4.0L OHV 4X2 and manual transmission. It has 137k miles on it, and only 7k on the rebuilt transmission. New clutch line, clutch slave cylinder and complete clutch assy.
My problems are unusually high idle when warm (900rpm, sometimes more) and when I start it up after letting it sit having been fully warmed up, it will chug like it has a high end cam in it, and when I hit the gas a few times it goes away. Also when it's recently been started, I hear a sort of popping/spitting sound in the exhaust that goes away as I run it a bit.
I'm thinking I have a pretty decent carbon buildup on the inside of my engine, and am considering some seafoam. Would carbon buildup cause these things?
what's been done:
new plugs and wires
new fuel injectors (motorcraft)
new IAC
new DPFE
new EGR valve, solenoid and tube
new 02 sensors
New upper and lower intake gaskets (and valve cover gaskets)
new air intake temp sensor (one in the manifold)
new coolant temp sensor (for the ECU)
new radiator, with fresh coolant flush and fresh coolant
new fuel filter
new fuel pressure regulator
By all accounts this sucker should be running near perfect, but my luck prevails, and it does not! Oh well, any ideas, let me know
