Hey guys just changed the cylinder head on my car its idling fine and starts up fine. As soon as I hit the gas it wants to stall out not sure why everything is plugged in. When I open the throttle a little the car will get up to 2500 rpm and if I hold the throttle. The engine will bog then get back to 2500 rpm and do it all over again.
I cant seem to find why its doing this anyone know the problem?

 

Ok so I figured this one out the map sensor and tps sensor where plugged into the wrong spots.

 

Classic mistake......don't think you are the first one. On the 6th gens the connectors are a different color (5th gens they are the same) to try to prevent this but it still happens. Glad you got it sorted out
