EGR Removal???

[89mustang]

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????

The EGR and AIR (smog) system are separate. There's no performance reason to remove the EGR.

Run the codes to see if there's a clue about your car's issues.

Good luck.

Leave the egr if you don't know what it does.

Your problems are related to something else.

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?????

The CEL need not be on for codes to be stored.

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.

Good luck.

Codes can be stored and the light not be on. 86-88 don't even hqve a cel.

Run them anyway...make surenyou do koeo, cm and koer codes

I thought if you removed the EGR you would get a cooler and cleaner intake charge?

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.
