Whenever I drive with the foot floored or whenever I rev above 4k while merging onto the freeway, my 944 knocks really bad. It almost seems like it is clogged or being starved of something. I dont know what else to do. CATALYTIC CONVERTER? O2 SENSOR? EXHAUST LEAK?
what I have done to try to diagnose it:
1) tune up: plug wires, rotor, sparkplugs
2) AFM: replaced it with a different unit since my original was making a weird noise
3) My Air Filter is new and My FUEL FILTER only has at least 2k on it. Before replacing it it had the ORIGINAL one from factory
****Keep in mind: I have the FRWILK Chip installed and I run 91 octane. The 944 was giving me problems like this before i installed the chip
thanks,,
