a couple of months back i blew my p.o.s. s/c impeller into bits and it all went in the cylinders it started knocking up high close to heads and it would idle fine but with a crazy tap.. well to make a long story short engine got open up heads came off, we found pieces of the impeller in there checked clyn. walls not one was scratched no bent rods. I send heads to check and had no bent valves either... heads went back in, i checked for compression all clyn. were around 180... we installed intake and turn it on engine idle very nice shut it down and started to assemble it back with its new blower a procharger d with intercooler...and that’s when **** hit the fan. we turn it on and the car went wild, back firing and I have almost a dead cylinder on driver side..... they told me its the maf since my old setup was not blow thru and this one is. might that be the problem? guys I really need you all help on this one thks victor
