Hi all first of all I am both new to jeeps and to this forum, so I apologize if I should've added this to a thread instead of created a new one. I just purchased a 2000 Jeep Cherokee limited with 58,800 original miles. Passed both MD and PA inspection recently. Had all new plugs and wires installed, check engine light came on a couple hours after I bought it. The seller drove if from Glen Rock, PA to State College for me so I'm wondering if it could be an electrical issue. I don't notice any strange sounds when it idles. Also the low beams don't seem to be working but the high beams are fine. I did see in another thread that someone seemed to have the opposite problem, but I'm unsure of exactly how to diagnose whether it's the bulbs or the switch. I have a receipt from when the own had an inspection done, and most major things were checked. Also I read that a loose gas cap can cause the light to go on so I checked that. If anyone has any idea what minor things could cause the light to go on or what major things could that I might not notice that could cause the light to go on might be. Id really appreciate it. Planning on taking the car to get looked at monday, but I'd like to see if I could identify the problem on my own. Thanks!

 

Get the code read. You can get lots of help here but not without knowing the obd2 code. Autozone will do it free

 

If you have an auto parts store near you like O'Reilly, Advance, or Autozone, they can use their code reader (free) and find out what Diagnostic Trouble Code(s) has triggered the Check Engine light.


Get the code numbers and post them here so someone can help you with the troubleshooting.

 

Yeah, knowing what the code is will get you pointed in the right direction. Get the codes pulled (for free) from Autozone or somewhere if there's one close by and post the code number here. Most places will also give you a printout of what the code means for your vehicle also.

 

Got the code it's a misfire on cylinder 3. I've read a lot about this particular misfire and a recall of a piece of insulation by the cylinder head but I didn't wanna mess with anything. The guy at advance told me to take it to someone ASAP because the sellar told me he put new plugs and wires in and that if the plug is already worn it could be a more serious problem. Now again I'm not too familiar with engines but I'll take whatever info I can get

 

what was the exact code number?

 

The code reader didn't say I think it was a cheap one for people you don't know much about cars. It's just said misfire on cylinder 3 detected. I'm having a shop do more diagnostics to find out exactly

 

Before you pay a shop I'd take it to an autozone or oreillys that has a code reader that will dsiplay what the code is. You can find out a lot just by knowing what the code itself is.
