New MAM & injectors
 

just installed a C&L 76mm and 30# injectors.
why would the engine (cold) not respond to the thottle and why does it pop back into the intake....after it runs for a few minutes it will run fine...I had stock 70mm and 24# before and it ran fine......this is on a '90' coupe and it is supercharged

I hope your new MAF is calibrated to your 30lb injectors. Check with the place you bought it from. If it isn't matched to your 30s, all you need to do is replace the sample tube in the MAF.

Yes it is suppose to be....the tube is colored purple per the instuctions
