Dear GM Customer Service

GM changed the EGR valve in 2007. Any 2005-2006 models that need the EGR valve replaced are supposed to be changed to the 2007-2009 style on the 3.4L. It requires a new EGR valve, a different EGR to exhaust manifold pipe, and a PCM recalibration.

can egr valve be the problem of cold start? when its -5 and lower the car not starts. it cranks but not starts. if you will touch a gas pedal a little bit it starts but first 2-3 seconds working not on all cylinders.
what is a part nr. for new egr valve?

Also, have you ever replaced the battery? If not, I'd replace it just because you're already on borrowed time, and it may not be able to produce enough current for the started to turn the engine over as fast as it should. If your have a 2006 Equinox, there's a good chance that it was assembled in 2005 and the battery is now over 7 years old. Make sure the replacement battery provides at least as much power (CCA) as the factory battery.

the battery was changed last winter. there is no problem with the battery 100%. its spining it like crazy!
and it happens only when its very cold. when its normal temperatures like 0--5 it starts perfectly.

can the starting problem be coolant temperature sensor? my car was sitting for 6 hourse in -1F. i went to see with OBD2 scanner for the temperature it shows and it showed me coolant temperature 23F. can it be starting probmel reason?
#17
It's possible. Was it sitting outside or in the garage? What catches my eye is the difference between the (ambient) air temp and the intake (air) temp. I might suspect a bad intake air temp sensor. Unfortunately, it is integrated into the MAF on the 05-09 Equinox 3.4L.

this is from today morning.2-3seconds aftr starting.
but the most funny thing that it started without a problem.

what i noticed that only 2005 2006 is doing that. crank but not start and continuing to spin. i did not found any thing from customers of 2008 2009 equinox. that mean that GM fixed it! and they know what to do! so why the don't share with the customers? i dont understand! all of 2005 2006 are out of warranty and people will repair it for there own money so why to hide it?
