I am getting frustrated with my 87 XJ. I am having a problem with sluggish acceleration and poor gas mileage. It passed the tough CA smog test for gross pollutors with flying colors, but it still has a loss of power. Prior to the smog test I performed a tune up which included:
-spark plugs and wires
-cap and rotor
-oil and filter
-air filter
-checked entire vacuum system (found several cracks and holes)
-fuel filter
-TPS (solved high and erratic idle problem)
-cleaned grounds (found the one from the block to the firewall hanging loose)
I plan on adding another one tomorrow on my day off.
-Dynomax cat-back exhaust (looked at cat and the medium was in good condition, the previous muffler was rotten)
This Jeep has been in my family since new, and I noticed the problem when I got it from my sister prior to the lift and tires. I assumed that it was in need of a tune up. So after a year and a half of building the Jeep in my garage, I took it out and was disapointed that the sluggish acceleration was still there. My sister had the fuel injectors replaced, 02 sensor, cat, and the head repaired (crack) a couple of years ago. She stated that she had noticed a power loss before she gave me the Jeep.
I have read the Renix Files by ECOMIKE.
I plan on checking the EGR valve, MAP sensor, and CPS tomorrow.
Please help, I have spent a lot of time and energy on this Jeep and I am dying to go play.
