My scanner is showing the baro reading at 130hz and 9-10psi pressure.
When I disconnect the battery and reconnect it resets to 156hz.
I have bought cleaner and clean the maf sensor and nothing changed. I bought a used maf sensor from a junkyard and it is reading the same numbers. I clean it also but no change.
short trim jump around between 5% to -5%
At idle long term jumps to about -10% During driving the long term actually goes to about -1% to 1% or even 0% but sometimes it hovers around -4 -5 percent.
Also I have to change my spark plugs about every 3 months or so because I start getting a lot of misfires. When I do change them. They look new except I have been noticing that the cermaic around the electrode usually has a hairline crack in it. But the plugs are clean almost like new. I used ford motorcraft plugs.
Any ideas?
