Specs to start:
1990 MJ - 4.0 - 5 Speed - 4.10s - 31's - 2" BB - Air filter - glasspack
I consistantly get 13 - 14 mpg. Doesnt seem to care if I baby it, or if I have fun, itll never break 15mpg, highway, city or anything. WILL NOT break 15mpg.
Had a friend behind me and he said it stinks, like a old POS. I smell that rotton eggs smell every once in a while.
Cats been off and its not clogged, not performance difference with it on or off so its not clogged.
I beleive im running rich, hence the rotton egg smell. Where should I go first, it starts and runs fine, just smells. I was going to replace the 02 sensor, since its $25 and its never been done for all I know. Then im going to go through and check every sensor I can. Anything I should look at specifically.
Also, another thing, whe its idling, it kinda hunts, doesny vary much but it sounds like is has a load on it, then nothing, then a load...
