Sputters on acceleration and under load. Idles good. Have replaced fuel pump (45-50psi), emptied tank and blew out lines. Replaced tps, map sensor, oxygen sensor, coil, distributor, cam sensor, crank sensor and ecm. No odd noises from engine, good oil pressure and runs cool. I am lost please help. Thanks

The first step should be reading and recording any diagnostic fault codes. Have you done that yet? Do you know how? How old are the spark plugs and wires?

Hi Atvextremist,

Here is a link to an article that features written step by step instructions and pictures explaining how to do the scan yourself, also I have included a link to our YouTube channel with a how to video on code scanning. Most scanners are inexpensive to purchase, you can purchase one online from sites like Amazon.com. Once you have the codes please get back to us so that we can further assist you. We are always happy to help.
