to start i have a '97 tj 4.0L with 237000 miles. in mid December the jeep seemed to have blown the engine. the amount of smoke coming out of the exhaust was embarrassing. as it turned out my 9th grade teacher is a jeeper so he came to look at it. he turned the key and it cranked but did not start. he popped the hood and did something under the hood then told me to start it.i had my doubts but when i turned the key it fired up and started
(faster than it ever had before) and i can't figure out what he did. (he said it was a trade secret) any ideas?
