So I'm driving today on highway at coast speed. Car has boosted 21.5 psi alllllllllll day and for the past week it comes a huge shower and now I'm at 12 psi and rich (10.8) ish. Checked all the lines from mbc to the turbo as well as the bov and wastegate no cuts leaks loose hose. Seems like something got wet???

 

Check intercooler Piping to make sure couplers didn't get loose.

 

Ok I will check that but it literally did it as soon as it started raining hard so I figured some was damp restricting flow but I'll check the couplers when I get home!

 

Mine does this after washing the car for about a mile after leaving the car wash...been looking for the reason as well...

 

How long does yours last bro?

 

Like a mile of driving...it wont hit more than wastegate pressure...or if I let it idle it runs super lean like over 18...

 

I'm guessing your MAF don't like water...

 

Mine is typically 21.5 psi with 11.4 ish afr at wot. It comes this flood and I now have 12 psi with 10.0-10.5 wot wtf I mean something had to had gotten wet it was the sane five minutes after it poured

 

Will the maf likely dry over night in garage you think or should I blow or wipe it off

 

spray maf cleaner on the maf, jsut watch out for the little red wire at top of the inside of it, thats for the heater wire. Other then that u mustve torn or loosened a coupler, im sure it was on the licp, thats where mine always pops off.

 

I'll check it all and hopefully find a problem I just got it running like I want it too. Go figure haha

 

There's a clamp off the lower icp into the ic but it's tight. Is that the prob?

 

Maf had alot of soot build up bot sure if that will fix it I will see in the morning and I tightened hose clamp I'll let ya know thanks!

 

Problem solved guys ended up finding two hose clamps loose on the ic system as well as the maf being dirty

 

I had the same problem. is this a common thing?
