Having a problem with my 3rd gen - it has some mods, hoses replaced with silicon, upgraded intercooler, etc. Stock turbos. Problem happned suddenly after accelerating under full boost.

-Found a blown off boost hose
-put it back on
-started car and have the same problem (figure plugs fowled)
-Replaced the first two plugs because that is all I could locate.
-drove car and still ran sour
-found other two plugs and replaced them
-drove car and exact same problem still


-I have fixed hose that popped off, replaced a total of 4 plugs and still no go.


Car smokes like a freight train, and when you give it gas the fuel/air meter freaks out and the car acts like it wants to die. It idles very rough and jumps around idling, and most of the time stalls.

 

Check the MAP sensor (it's located along the firewall on the drivers side).

Make sure it's vacuum line is connected. After that, reset the ECU.
