Ok if I don't start my 2000 blazer at least once a day it's HELL to get going. It's been 3 days of trying and checking fuel and ignition. It rolls a great plenty and once in a while it pops off but doesn't start. and 70% of the time when I let off the key it still rolls a couple of times like it might start but then stops. I does seem to be worse now that its cold out. Also I just replaced the TPS didn't seem to make any difference but It was throwing a code and for $35 I changed it out. I read the sticky post and was wondering if anyone had thoughts and for the life of me I cant remember what EGR stands for.

 

Exhaust Gas Recirculation.
