79LilRedExpress Posted July 15, 2020 Report Share Posted July 15, 2020 About a month ago got on an entrance ramp and car wanted to stall. Went to limp mode????? Got to a garage. Idled rough. Guy scanned it. Crank sensor, cam sensor, cyl 1 misfire, evap leak. Asked if i just put gas in it. Just did about 35 miles ago. Said he had 10 complaints in last 3 days for bad gas. Put in fuel system cleaner. Drove ok except at around 30 to 40 mph and 2000 rpm. Felt like it had trouble figuring out what gear to be in. After about 50 miles car drove fine. 2 weeks later call shut off at a stop light. Lights came on again. All the same codes. Bought a crank sensor from autozone. Replaced it and took it to a shop to have it relearned. They said ran great. Got in it the next day to pick it up. Light comes on, crank sensor. Shop saud get an oem. Put an oem in. Started right up and ran fine. Had shop relearn for free. Noticed the car kinda hung in gear longer before shifting to final gear. Drove it about 1000 miles. After about a 2 hour trip got in car to back out of parking spot and car was kinda surging like transmission wasn't engaged. Drove a short distance and at a stop light pressed the gas and it wouldn't move, then surged. Drove it back home. Runs fine in higher gears at highway speeds. Next day went to put it in garage and it was hard to put in drive with foot on brake. Car surged a couple times pulling in garage. Fluid smells fine. No metal on dipstick. However, there is fluid coming out of the dipstick tube. Its all over that area of the engine compartment. Not sprayed, maybe misted of just running down dipstick tube. Car has 140,000 miles on it. 2010 base model with 2.4l. Well taken care of. If it waa an older car I'd have an idea where to start, but not familiar with the new stuff. Grew up on muscle cars. Diehard Mopar guy. Any ideas? Thanks! Quote Link to comment Share on other sites More sharing options...
Summer Solstice Posted July 15, 2020 Report Share Posted July 15, 2020 You don't mention having ever done a fluid and filter change. That would be a good place to start based on age and miles. Quote Link to comment Share on other sites More sharing options...
OhareFred Posted July 15, 2020 Report Share Posted July 15, 2020 What had to be “relearned”? Changing the crank sensor should not require any computer relearn, right? Did the shop do something with the computers? jkeaton 1 Quote Link to comment Share on other sites More sharing options...
79LilRedExpress Posted July 16, 2020 Author Report Share Posted July 16, 2020 The fluid and filter have not been changed. According to a tech the crank sensor needed to be relearned. I tried a sensor from autozone and the car wouldnt run tight. Only after I put the one in from ma Mopar did it fire right up. Think the relearning process could have messed up the transmission controls? Could it just be a dirty filter? Easy to pop the pan off and the valve body for inspection if it has one. Been a pretty good car till now. Quote Link to comment Share on other sites More sharing options...
Summer Solstice Posted July 17, 2020 Report Share Posted July 17, 2020 You are overdue for fluid and filter. A relatively easy and inexpensive scheduled maintenance item. Yes, it may cause minor problems like you are experiencing. You will also have the opportunity to examine the pan and fluid for any evidence of wear. jkeaton 1 Quote Link to comment Share on other sites More sharing options...
