The car surges under normal driving conditions but if I turn off ignition while driving then back on the engine light goes away and the car then runs normal with no surging but only for a little while. I have replaced coil pack, injectors, fuel pump and filter. I have checked and there are no blockages in the fuel line also replaced crank sensor and timing sensor. It feels like the fuel delivery cannot keep up it is obviously something electrical as when I restart its fine. So any advice would be great. Can the accelerator pedal position sensor be of any issue?

Sounds like a code is stored in the computer. Take to most automotive stores and have the ECM scanned.

Hello SHAWNREAY1976,

I am sending you a link that if you decide to conduct the scan yourself it will be a great help to you. The link features an article with 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.

This is applicable even if your check engine light is not on.

Most scanners are inexpensive to purchase, you can purchase one online from sites like Amazon.com
