Customer Question

My truck runs fine till it warms up then it runs rough and is losing power when you accelerate. We have changed the oil in it and it runs fine for about three days then starts running rough again. My check engine light is on. But goes off after the oil change then comes back on when it starts to run rough again

Hello and welcome to JA...before we begin I need to know the year and model of your vehicle please.

Ok..... The best way to approach this is to have the system scans for trouble codes... You can go to Pep Boys or AutoZone or Advanced Auto... These stores will scan the system for free and then you can tell me which code or codes are stored in the memory of the vehicle so that I can better assist you in repairing it... Can you possibly go to one of these stores and have the system scan and then tell me what code you have just don't let them sell you anything when you go there just have the system scanned and let me know what codes are there.
