Hey guys hoping you can help me out with this one.
Brief history- Engine in this was changed out for one with less miles and NO lower engine knock
Other then minor things here and there it was running great up until about 3 weeks ago.
It started with a little hesitation as you were driving and only lasted a second or two. It grew progressively worse as time went on. It doesnt do it all the time and i cant recreate this issue at will.
It generally wont do it in the AM but on the way home in the afternoon i get about the same distance (with a few miles) from work and it starts shuddering and acting like its not getting any gas. It will usually stall at that point (65mph) forcing me to throw it into neutral and hope it starts, or get over on the side of the express way and let it sit for a min or two and then it starts back up. It seems to be just getting worse. Occasionally i cna feather the gas and then floor it and it will stop shuddering. The other thing that may or may not be related is my Tachometer will be working fine then start jumping up and down then just bottom out. Im pretty sure the engine is not revving to 5.5k on the road as the engine noise does not change.
Here'* what ive done so far:
-changed Fuel Filter
-checked plugs (correct gap - no signs of wear)
-changed Coolant Temp Sensor
It is throwing CE codes:
P0300- Engine Misfire Detected
P0341- Camshaft Position (CMP) Sensor Performance
P1200- Injector Control Circuit
P1362- Ignition Control (IC) Circuit Low Voltage
Now I have another camshaft sensor and was going to just change it out, but could it really be the sensor or it is throwing that code because its misfiring. I actually have one of everything off the other engine.
i was told it could be a plugged converter, as converters in the past have always been a pain and more expensive I was hoping for some alternatives
the other thing someone said was the MAF could be bad, again expensive so im hoping not.
Thanks in advance.Hopefully i covered everything
