I bought an 04 TJ, ran great did some mudding and baby crawling lol. Anyways now the throttle positioning sensor went out, or the code jeeps coming up. I changed the sensor and everything seemed fine for maybe 50 miles or so.
Then when I got up to around 50-55 mph the alarm and check engine light starts going off. I check the codes and it says throttle pisitioning sensor and number 4 cylinder misfiring. So I fix both of those, now still having the same problems and codes. What could be the cause of this and or how can I fix it? I can't keep buying parts with no fix to the problem lol.
Please help if you have any info, thanks.
