Do I have to rebuild my engine if codes P0300, P0113, U0121, and I think code P0131 shows on my 2007 dodge durano 5.7 hemi engine and what is the cheapest price?

Asked by Mar 12, 2016 at 09:05 AM about the 2007 Dodge Durango SLT

Question type: Maintenance & Repair

I have a 2007 Dode Durange 5.7 hemi. My truck was working fine until I
drop my child off to school. I try to start it. It wouldn't start. Now I was so
stress that I didn't put any oil or coolant in it. Took my truck to 5 different
mechanics. All the mechanics said my truck will not start and I need a new
engine except for one mechanic. I had it towed back to my house. My
neighbor and I kept putting oil and coolant because it was so dry. Within a
week, my truck started and was running. Little by little, the suv would run
for a while, then cut off. I was able to drive it out the driveway and parked it
on the street. P0300, P0113, U0121,codes are showing up (and I think
P0131). I had it towed to a relative house that was suppose to fix it. Instead
of fixing it, I just found out it has been sitting for about 7mths now, but It still
starts and run.

Rebuild your engine? Probably not. P0300 is a general misfire code, P0113 is an IAT, or Intake Air Temperature sensor and U0121 s related to the braking system. P0131 is an oxygen sensor code. I would find another mechanic if they want you to replace the engine. I would drain the oil and coolant and add new and fix any leaks. Take the truck to a decent mechanic to get your vehicle running like new again. Might mean a diagnostic charge and a few sensors and parts.

Thank you so much. If you don't mind me asking, approximately how much should I be expecting to be charged for a decent mechanic services?
