I too had a runaround chasing Jeep parts the last two days. I pulled the codes out of the computer on my 91 EFI system and came up with a MAT sensor. I checked it out the best I could with what I have to work with and everything points to a faulty MAT. So I go down to Advance to buy one. "Sorry we can't get that", they say. "What? I know you have it on the website", I say, "I looked it up". The kid goes through everything again and says, "nope, can't get it". I give up and go to Napa, None in stock. The heck with it, I go to the Jeep dealer, "we can get it tomorrow it's $43"! Ouch, over twice what Advance wanted! I went home and mowed the grass and dug some ditch for exercise. WooHoo! Fun! After dark, I pulled up Advance Autos website, look up the MAT sensor and there it is, big as day, even has a picture! I wrote the numbers down for the two they have listed and stopped at Advance this morning on my way in. It took 20 minutes of backwards manipulation to cross reference the sensor and for some reason it is only listed as fitting 94-97, but seems to be the only one listed for the 4.0L 91-95 engines. So we ordered it. Hopefully it will fix my check engine light and I'll be back in business. It was only $20 at Advance. I still have not heard back from coil spring specialties about the quote on my springs. Russ mentioned the Javelin Springs. I would love to have set to try and have tried several times to score V-8 American or Javelin springs to try out and have always been shot down by high prices by sellers. For the quotes I've gotten on used springs I can buy new ESPO coils! If I'm experimenting I don't want new coils and have to wait for them to settle in. I'd like to get a used set that have allready been worked and are about where they will stay so I can see what I'm up against. Rains are supposed to be moving back in, so I'll have some inside time to put the new motherboard in my home computer and get the sensor in the American and maybe even hook the heater control cables up! It's the one thing I've never managed to get around to yet!
