I have a 03 636 changed the head gasket but it all back together and started up first try..sounded good revved it up a lil not too much and as soon as I took off it kind of bogged didn't think nothing about it I switched gears and it bucked on me bad so I let off tried to take off again it started bogging and bucking and than it finally took off on me wat do u guys think it can b???

Tried new coils new plugs new tbs new harness new ecu new cam sensor..but the throttle bodies I ended up getting didn't have the secondary sensors on the right so I put mine on can it b that

Anyone have any ideas???
