HAVE JUST HAD MASIVE PROBLEM TRACEING stalling, FUEL STRARVEATION / FLOODING PROBLEM ,TAKE OFF YHE AIR FILTER LOOK DOWN THE INLET MANIFOLD WITH A MIRROR AND TORCH . IF WET INJECTOR SEAL PROBLEMS (COMMON FAULT) CHEVROLET DO A MODIFIED INJECTION UNIT TO INTERCHANGE, ABOUT £300 AND 3 HOURS TO INTERCHANGE,YOU CAN CHECK AIR FLOW SENSOR OR MAP SENSOR BUT MORE LIKELY THE FOREGOING jlwimports@yahoo.co.uk
