“hesitates on the execration”… Happens sometimes…Try Prune juice or getting more fiber in your diet…these things can happen in life. More fiber, more fluids and your “execration” will be fine…Uh…wait a minute what am I talking about again?
HA…Sorry…I had to…P0335 is a crankshaft code…this is or can be important because the ECM uses this info for running the engine ignition system…and you are probably having an engine miss as a result. You need to first check the mechanical timing on this engine…and I am wondering what codes you had Before this “New to You” engine… Im talking about the t-belt and the timing it provides…it needs to be spot on…not off one tooth or suspect of belt stretch.
I would start by cleaning off that crank sensor…and or testing it/replacing it. I would also check the mechanical timing of the engine…Put the engine at TDC and line up all the marks…be sure the crank and cam marks are alligned…if they arent you will see these types of codes.
You can also glean some advice from this link.
