From my experience, P0106 only comes on when driving hard. If I drive my P5 like a grandpa and don't rev it out, it won't come on.P0171 & P0106 are the only two coming up. Literally just picked it up a couple of days ago. Was planing on taking care of all that this weekend to narrow it down.
I have an aftermarket Injen intake, could that be causing my P0106?Those look like air leak codes....like the accordion rubber intake tube is cracked or vacuum line cracked or off where it should be plugged onto. Neither of those codes speak to AT light IMO. Hard shifting might be fluid level, fluid age, valve body or filter issues or possibly torque converter issue. Start with easy stuff, pull accordion piece off and look for cracks. They can be hard to find on the car. Check all under hood vacuum lines and condition. Try to spot something out of place. Check trans fluid level and if clearish or burnt looking. If you don't know if or when fluid has been changed then change it or have it changed. Go from there..................
probably not. I have the crc intake from vendor here that boxes in the filter above the cai hole instead of having filter down low behind fog light. i will get occasional 171 in winter when air is colder/ denser but when humid and warm it is fine. 106 seems more vacuum line or egr tube according to fsm shown above.I have an aftermarket Injen intake, could that be causing my P0106?
