[QUOTE="97svtcobravert, post: 15540622, member: 184706"] Hi everyone, My 97 Cobra has a hesitation under load when driving in high gear/low rpm. In 5th if I am cruising and say I am going at like 60 and rpms are under 2000 rpm and I floor it the engine hesitates. Also does it in 4th when rpms are low. It idles fine and pulls fine when taking off rowing through the gears up to red line. The IMRC seems to be transitioning as I feel the surge above 3200 rpm. I have replaced wires, plugs, coils, air filter, fuel filter 10k ago, cleaned MAF sensor, tried techron, seafoam intake. When I first did those above it seemed to clear up, now it has returned after sitting for a month while winter weather is here. I am thinking about trying That CRC induction cleaner for gdi engines since they suffer carbon build up behind the intake valves, like the IMRCS do. I just wanted opinions if anyone has tried that product vs seafoam. I appreciate all responses, thanks. [/QUOTE]
