1996 Jeep Cherokee CODE P0117 and P0300??

Question

Hi, I got a 1996 Jeep cherokee classic (2 door) 2wd 4 cilinders (A/C dissconnected) I took it today to autozone but they seem to not know what this codes are... the codes I get are the P0117 and P0300 and I have the check engine light on... pls help and if you can pls also include a brief explanation of how to repair the problem will help a lot. thank you very much.

When driving it gives me kind of a stumbling... you can barely notice it... it was more noticeable until I changed the air filter. other than that everything seems fine.

Here is the site to decode the numbers.
P0117 is low voltage to the coolant sensor. Could be a dirty plug in the wiring.
P0300 multiple misfires. Bad rotor, cap, plug wires, sparkplugs, or a combimation.

Answer 2

Don't know why they couldn't tell you what the codes mean, or why they didn't seem familiar to someone with 20 years in the business. These are standard SAE codes, they are not Chrysler or any make specific. P0117 is Engine coolant temp circuit low, and P0300 is Random / multiple cylinder misfire detected. On the surface, they seem unrelated. What are your driveablity probs?

Answer 3

those codes dont sound familiar to me but anyway,
first off, going to auto zone for mechanical diagnostics is your first bad idea.
The codes need to be decoded by someone who is familiar with Chrysler codes and has access to the Chrysler trouble shooting sites.Where they can type in the code from the computer and get a description of the problem.
Auto zone is great for parts but most times they have some young inexperienced punk trying to do things they are not qualified to do when it comes to diagnostics.
take it to a reputable mechanic shop and I am sure they can decode the computers trouble codes and give you a answer to whats wrong.
Should only cost you around $50.00 to have them trouble shoot it for you.
