Crank sensor?(and ECM function questions) 2.7
Car has been back on the road for a little bit now. Have about 1,100 miles on it. I just did the valve seals, lash adjusters, timing chain, water pump, oil pump, ect. Engine has been acting funny off and on.
At times, it idles rough. Sometimes it stalls when put into gear from a stop(like from reverse to forward). At times it runs awesome, shifts great, idles smooth. Other times it runs rough(like a miss or running out of gas), shifts early, and idles rough. When its acting up, it shifts way early and looses all power at higher rpms. When I say its running "rough", I mean it feels like the engine just dropped a cylinder. Obviously it hasn't since it comes and goes. There are no noticeable ticks or clunks coming from the engine.
With the shifting, its weird. It will act like normal. Will downshift with a little snap of the throttle, shift at normal points. At times, it shifts into 3rd before 20mph, and I have to literally floor it to downshift.
NO CHECK ENGINE CODES
Could this be problems with the crank sensor? Or should I be checking my fuel system over more?
