Hi all, i have an 88 cherokee limited auto trans and about 200 k on it... it started off it would run fine but if i shut it off and started it again while still hot it would stall out on the freeway and at stop lights... sometimes getting "stuck" in a pattern of backfires and really rough running and no throttle response. after a minute or two it would just start going fine again for a while. it kept getting worse and worse till now it starts and runs till its warmed up... about 190 degrees and it runs like poo for a few seconds and dies
.. it fires right up like normal once it cools all the way back down. right before it dies it starts back firing and missing really bad.
i've replaced the cps... twice just in case
i also cut out the plug and soldered the wires
new ignition coil
new icm
new plugs and wires
cap and rotor have maybe 5 k on them
egr is disconnected
i've fallowed the o2 sensor and cts to see if they were shorted some where and nothing
also tried unplugging them
there is no spark while cranking from the coil right after it dies
i have fuel pressure tho i dont know how much i'm pretty sure its a spark and timing issue tho
theres also a smell of gas when it dies
i might have done more i dont remember... but i'm really stumped here and any help is much appreciated
thanks
