Diagnosic codes 72, 73, 25
I drive an 89 F-150, 302, 150k miles. I have been having problems with jerking and shaking while driving, and loss of power when accelerating. I won’t post details here because I just have a specific question about some diagnostic codes that I got. For more specifics on these problems, please see my other post (search for user:jkbk17 or subject:“89 F-150 jerking, check engine light flashing”).
In a KOER test, I pulled the following diagnostic codes:
72: Insufficient MAF/MAP change during dynamic test
73: Insufficient TP change during dynamic test
25: Knock not sensed during dynamic test
Does anyone have any ideas what would cause these codes, and could this be related to the problem I described above?
Thanks!
Jeremy
