I recently deleted my egr solenoid. will this cause the car to run rich?? i also took off all the air pump stuff and left the pump plugged in but looped the air hose back into its self.. and added headers and throttle body. i left the little solenoid on the driver side plugged in also. im waiting to get a retune but im wondering if doing all the things i listed above would make it run rich?

the car runs nice when its cold but when i heats up it runs really rich and dies out.idles rough also but thats prolly the cam

What made you come to the conclusion that the car is running rich? Do you have a wideband? Are you monitoring the O2s?

You don't list your mods other than you have a cam. Did you get it tuned for the cam?

Details, man.

I listed all my mods on a previous post and you told me they were all missmatched.. but anyway. 383 internally balanced eagle rods and crank srp pistons.11.3.1 cpr..has stock lt1 heads with new valve job 1.6.1 comp cam rocks cromemolly pushrods. studs and guide plates. twin 58mm lingenfelter 44lb injectors . pacesetter LT. cc503 cam, i cant remember what spring.. but anyway. the car was dyno tuned with all those mods except the headers and throttle body...So all i changed was TB, headers and egr delete

I pulled three plugs and there pure black and all i can smell is fuel in the exhaust.

I was reading old post and their saying deleting the egr can mess with the computer and make it dump more gas.. oh! and coolant bypass along with the bolt ons i just did

Was it tuned for those bigger-than-you-need injectors?
You may as well pull the AIR pump off. And, no. Deleting the EGR won't make your car run rich. I would make sure the coolant temp sensor is plugged in, and that the connector is in good condition. If you don't know, that is the little 2 wire sensor on the water pump, driver's side.
Hope this helps.

So, was it running fine before this i'm guessing?

Z28harcor

yes the car was tuned for the injectors. and yes it ran fine before i deleted the egr and air pump tubing,headers and throttle body..it could be a number of things at this point. i checked the water temp sensor wire and its good no ses lights either

You may have just had a temp sensor, MAP sensor, or MAF sensor fail. May net be anything you did. Somebody that knows what they are doing needs to scan it for you.

I left something out. The throttle body I put on it was for a tpi so I bought the tps pigtail and wired it in. I was having trouble because they put the wires in the connector wrong to when I gave it gas the volts would go down instead of up. I think I got that fixed. I set the volts for .7v at idle and it goes to 4.8v at wot. Maybe this is the problem
