TPS adjustment (throttle position sensor)

[88AMComanche]

I hade an issue with my fuel pump recently, but before i knew that was the problem....I tinkered with the TPS to see if maybe that needed adjustment maybe :doh: Which ofcoarse it didnt. So I installed and triedlining up the marks i put on it with a sharpee but it still seemed a bit off & took longer to start......Long story long,I finally got it where it seems to start at its usual 5 seconds of cranking point. (wish it'd fireup on a dime) ........ My question is: IS there wa sway of adjuting the TPS? I just set it where it starts fairly normal & runs normal. When i say normal i mean within 5 seconds or so of cranking. The TPS has adjustment slots,yet i havent seen any info on adjusting it and would like to know what the deal is with it if at all possible. thanx.

What year MJ do you have? If It's '90 or older and a 4.0 the adjustment can be found here: http://www.pirate4x4.com/tech/billavist ... manual.pdf the settings are different for Auto and Manual trans.

Thanx ............I suppose I will have to buy a Volt meter.Seems to be something that is needed fairly often on the Comanche. Dang,I was hoping there were more simple "no equiptment needed" instructions to adjust it :bowdown: Such as ....adjusting it by ear or a certain method based on Rpm & cranking or something like that. But Ok....I will put a Volt meter on my list of things to get~

But those division figures are quite intricate & complex in my opinion. I guess the math part of the job would be the hardest,But ty for the link. helpful stuff there.

Not to go OFF topic..........But does anyone remember the Amc/Jeep Eagle? IMO that was the vehicle that started it all as far as FAmily SUVs go. 4wd , yet looked like a family sedan/station wagon :bowdown: those were Coool
