I have a 1999 Wrangler 4 cyl., and on occasion when i let it sit and rev for about 5 mins it starts to bog down like its going to just shut off. It never shuts off but it doesnt sound to good. Also when im in 1st gear and i am pressing on the gas it doesnt feel like fuel is going thru the lines, and the jeep doesnt accelerate. Anyone else have this problem?
Also i do use 89 gas in it, but it doesnt seem to help anymore then 87.
