over the past week i swapped in a 4.5L stroker built off a HO motor into my 88 jeep
drove fine the first few days, not i have a VERY weird stallin issue
for starters, the jeep has no exhaust as of right now, and it is running rich, but not terribly rich. I have the 88 fuel rail on it, 39psi FPR, HO throttle body, used the 96 TPS (cut and spliced the connectors) but its only putting out 3.55v at WOT (i have a new TPS going on soon). I check the CKP, its good, CMP has a high altitude setting, i dont know which it was on, it was running so i left it. the motor is a 4.5L 9.8:1 compression 260/272 crane cam.
When adapting i moved the temp sensor from the renix block, to the HO tstat housing, i also put one in the radiator, and one in the back of the head.
Now, the issue, when the jeep is cold, it seems to drive fine. I just drove to the gas station, no issues, shut the jeep off, when i got back outside it wouldnt start (just went in for food), waited a few min and it started up. got about 200 feet up the road, stalled, waited, and it started (if i dont wait it just cranks). it probably stalled 4 times on the less than a mile ride home.
when it stalls, the tach instantly drops to zero, even tho i was probably doing 30mph and it was still in drive. this leads me to think its the body to block ground, but its clean and tight, so are all the other grounds on the block.
As of right now like i said theres no o2 sensor, also no knock sensor, both will be hooked up tmrw, and neither should cause this type of intermetint issue
IIRC, the renix jeep can run with out the CMP so i think im going to try with out it to see if that high altitude thing can be causing an issue.
Ive been reading the other threads about renix issues, but this is just baffling me
thanks in advance
