Sometimes you can tell that a converter is clogged because you don't go any faster when you push the gas pedal. Also, there usually is a noticeable drop in gas mileage associated with a clogged catalytic converter. A partially clogged converter often acts like an engine governor, limiting the actual RPMs to a fast idle. A totally clogged converter causes the engine to quit after a few minutes because of all the increased exhaust back pressure. :brows:

hmmm...ill check that but i think its fine...replaced it last year for emmissions purpose :mad:

 

all suggestions are helpful to narrow it down :cheers:

By chance did your MAP line pop out of the side of the TB. Mine did & I experienced the exact symptons you pointed out originally. Plugged it back in & it went back to normal oper.

Are you getting fuel in the combustion chamber? are your plugs moist with fuel when you pull them?

[Ben-88Comanche]

if you have fuseable links, check them. One of mine was bad and when you turnedf the key to run it would die, but maybe yours is just a weak connection or something? pull on them to see if they come apart, if it stretches, replace it

Do 87's have the crankshaft sensor? My 94 4.0 started falling all over itself and it was the crankshaft sensor.

Yes, they do.

-yea the plugs got fuel all over them so i switched them out with a new set

-MAP line is good

-Crank sensor is brand new

 

Ill check the fuseable links..never thought of that

I'm gonna go with this too. I had th same problm as bn. Rlease key to run and it would stall. Mine was actually a bad wire next to the fusible link near the battery

ITS ALIVE!!!!!

 

Re-checked the timing and it was slightly off...spend 30min trying to get it right and first flip of the key she fired right up!! I'm so relieved that it runs but now about 1500 RPM it starts to stumble and backfire...and ideas on that??

[mvusse]

Timing is off. Too far advanced.

[offroader461]
