intake gasket

I'm currently changing a 94 D90 from ECU control to carburetor I am using an Edelbrock 2198 intake I have seen that you shouldn't use factory intake gaskets any help?

I can't see any reason why you shouldn't use a factory intake gasket. I also can't see why on earth you would want to convert to a carburettor. You may as well install some leaf springs while you are at it.

I wanna say there was a difference in the coolant ports of the edelbrock to efi manifolds.. Just compare the 2 to see that they are the same.. I have both here and I can check the coolant routing tomorrow..

The reason I am changing to carb is that the ECU went out and just try buying one of those

You can get them for under $200 used. What's wrong with your ECU?

You will spend a lot less finding a ECU rather than buying the intake and carb.......

Had a severe over fueling problem sent ECU to repair shop and they said ECU is pulsing injectors every time and was the problem but they didn't have parts to repair bought one online and wouldn't even crank that's when I decided for carb

I doubt your ECU is the problem. Just a guess, but your coolant temperature sensor is probably bad causing it to tell the ECU that is very cold out making it run at full rich.

Check the resistor on the mass air harness should be 6.8-7.3 ohms if remember . Often over looked and will cause you to chase your tail at times .

Did you do a drag test on the pins for the coolant temp sensor? Those connectors often get corroded or break. Its just a standard GM fuel injector connector. You really should consider not doing the carb setup. You should be able to fix your fuel injection issues.

Don't mean to hijack but where can you find an ECU for less than $200? I need a 14CUX and not had any luck.
Thanks
