Approximately three weeks ago, my liberty diesel with 163,000 began to run as though it was down a cylinder. After checking a readout from my scan gauge, It said cyl 3 had a misfire so it was assumed that injector 3 was bad and replaced. To no avail, the jeep was brought to a local dealer who flashed the computer and attempted to calibrate new injector. Since the jeep did not run any better, it was towed from dealer to my home.
My question is could a bad crankshaft sensor make it act as though it was down a cylinder, supposedly had air leaks in fuel system and a bad map sensor. It does not appear that any rocker arms are broken. Or did it jump time? The dealer’s printout showed all codes that ever came up while driving the jeep over the past 7 years.
Are there any auto parts stores that rent code scanners/flashers that will work on Liberty Diesel in Connecticut? Any suggestions would be appreciated. Thanks.
