i have a 1990 xj with 210000 miles 5 speed. it misfires in mid rpm range with the throttle about halfway . full throttle and if runs fine. putting around does fine but the average getting anywhere if backfires like a mother. i know its a misfire because i put a timing light on it and just to see if it missed out and like every other rotation of the crank it would fire. i already put a throttle position sensor and crank position sensor in it from what i read here but still missing out. im lost so please any info would be great. thanx
