Problem

[vdrive502]

My truck starts and runs at idle fine but when you step on the accelerator it falls flat on its face and will not Rev up only a little bit. This was in a accident and rolled over what could the problem be?

Welcome to the Org.

gonna need more input. which engine?? which year?? blah blah blah....

[vdrive502]

It is a 2000 supercrew f250 7.3 automatic I replaced the fuel filter already. There are some codes about the exhaust having low pressure.

does it miss when trying to rev up, is there any kind of smoke? need more info on what the engine is doing..

[vdrive502]

Yes it has a very bad miss and will not rev up and smokes a lot and will also backfire if you put it to the floor.

was the truck up side down very long. if so when it was fliped over did you try and start it. because if the cylnders started to fill with oil and it started you may of bent a rod or bent a push rod if a push rod or rocker arm brakes it will run but make a poping noise..
