We just had 3 feet of it week ago. i popped engine light on high rpm in 2nd gear today. p0103. erased it, poped p0101 in pending next vehicle drive cycle. erased it. still getting maf codes, anything else? or is it from the intake. i dont think it is cause it never did this before.

Pull the bumper cover and get out the soapy water, this time. If you still don't get it, just take it in. It's been way too long.

Wow. Longterm that high is crazy, but you've been driving like this for a while. You have to find the leak. Post a pic of your hose and TMAP sensor on your coldside pipe.

Just take it in. It has been too long for you to be driving around with it like that.

This is scary.....

Wouldn't that intake on a stock tune hurt the fuel trims just as stated? Do you have a downpipe?


Tune............

ok, still having some troubles, was out of the country for a little while an left car parked. checked, now have p2178 as my only code at this moment, also get low coolant light on cold start every time. coolant is at proper level. still getting lack of power, very noticable when cold, did find lower map sensor leaking and repaired with new o-ring. never got nothing done with fuel injectors because they never looked at it, will rebook an they will check for hpfp oil leak an the fuel injectors next visit.
