I just bought my 1998 jeep cherokee 4.0 automatic about 2 weeks ago, was running fine for the first week and now its running like garbage, the CEL came on and I got it checked out. The code was PO171. The truck has 240k on the body and the previous owner said the motor was replaced and now this current one supposevely has around 80k on it. 2 days ago I did a full mopar tuneup, cap rotar plugs wires air filter and I reset the ECU. The truck was running great for about 15 hours and then on day 2 it was back to how it used to be. Running really rough. At idle my truck clanks around like it wants to stall but the RPMs are normal. The truck has a very strong fuel smell like it is running very rich and also the MPG are wayyy down. Any help on what I should do? This is my only veichle. Thankyouu
have the same problem?
