Low power, slight shake.
So recently i have been having a low power issue, with a slight but noticeable shake from the motor. I ran all AE tests and everything was ok. I did have a p0470 code that i cleared that has not come back. AE is also showing ebps at 18.63 KOEO with map at 14.5 and baro volts at 4.56. I dont want to just throw sensors at it. Any ideas? Thanks

I'd try cleaning the EBP first... be careful to use the proper procedure for removal or you will damage the plate it's mounted on. After a good cleaning of the sensor and the tube to the sensor, (look for leaks, too) Take another reading. The MAP and EBP are supposed to be within 0.2 PSI of each other.

Well i cleaned the sensor but i couldnt really clean the tube that well. The sensor was packed solid with soot. AE readings are still the same. No codes either. I called the international dealer for a sensor and tube, they have 3 different listings for the sensor, and no listing for tube. Ford wants $114 for the sensor, and $70 for the tube.

So i put a new tube and sensor in it, old tube had a crack. Ebp now reading equal to map KOEO. But the shake and low power is still the same, a little worse if anything. Also my coolant temp sensor is reading 302 deg when gauge on dash is at 1/4. Once engine is fully warm AE shows normal operation temp. Im gonna pull the valve covers next and check uvch connections, and probably do a compression test. I hope its not injectors, i dont want to spend 2 grand right now...
