Hello, All,

I had to fix the coolant leak on My 2005 Stang GT and I removed and reinstalled the manifold, I also replaced the Manifold with IMCR, Gaskets (upgraded to 2007 all plastic Manifold version). did a vacuum test with propane and smoke.

when I start idle stays between 1500- 2000rpm, and if I give gas it will stall, it also smells like gas and plastic, after stalled it will turn on only if i press all the way down on gas :oops:

This are my OBD2 readings, anything looks wrong? :confused:

I finally figure it out, If you see in the screen capture of the OBD2 reading it says coolant temperature -40, so I followed the sensor cable and find out that was connected in the wrong way
