Intermitant Stalling and Hesitation

[48wilys]

I have an 88 MJ with the 2.5. In the morning when I start it up it will run for about 5 mins, and then stall. After that I am lucky if it will run for a minute after I restart. If I keep my foot on the gas just a little, it will stay running. Also until it warms up it hesitates, and will buck at just about any speed. I have notice that the dash lights flicker just before it dies, but I am not sure that it is realted. It seems to be worse when it is wet.

 

I have tuned it up, replaced the fuel filter, EGR valve, coil, and a broken wire in the harness. I have good fuel pressure from the pump all the way to the TBI. I am lost and could use some help :headpop:

 

Thanks

disconnect the O2 sensor and see if the problems go away. If yes, replace the sensor.

Thanks for the O2 info. I disconnected it this am, and ir seems to have solved the problem. I am going to replace it tomorrow.

 

Again thanks for the help

Glad to hear....

 

I had the same problem on my 87, and chased it for months trying to figure it out.
