I no longer have a smog pump, and read that without it I should remove the egr also. Lately my car has been hard to start cold and runs at about 225 degrees!! Could the egr cause these problems????
Thats the problem< My check engine light is not on ( no code to run)?? tried plugs, timing, got a 3-core rad., and black magic extreme fan with shroud! car still heats or runs hot and hard as hell to crank cold?????
If you provide more info on the mods to the car and the exact issues it's having (when does it run hot, how you are able to finally get it to start, etc), then we can probably help more.
The EGR functions at part throttle to insert inert gasses into the chambers. This allows less fuel to be used and more timing to be used. Pumping losses are also diminished.
The EGR is non-functional at WOT so all-out performance is not hindered.
