my buddy just intalled some lt headers and x pipe and the car will crank but wont stay running. he didnt hook up his o2 sensors and that is prolly it but idk. help please

 

Did he hook up the front O2 sensors???? You absolutely need those!


Assuming he did, then it could be a number of things...plugs, wires, coil packs.

Does the car smell like it is getting gas? Is is starting and stumbling? Idling rough? How long does it run?

 

dummy forgot to do some simple stuff thanks for the help tho
