i have a 97 hatch with a b16a2 swap... today i was driving home casually and i was going uphill so i down shifted obviously to make it up the hill that is when i lost one cylinder so i pulled over let the car idle for a few minutes then i turned it off to check my spark plug wires fuel injector wires etc everything seemed to be good turned the car back on to find that its running on all cylinders again... i don't know if it threw a code since my CEL is always on i decide to scan it anyways but the codes that i already knew of were there (p0453 p0450 and p0133 which comes on randomly) so i just erased the codes and when out for a drive now i find that between 1500-2000 rpm i get a weird rattle sound coming from the left front tire area when im not moving also the my exhaust sound way different and vtec sounds louder but the crossover is not the same... anybody got any ideas? the motor has around 60k or so miles and im running a P2T ecu which i have already reset.. i also asked the gas station that i filled up today at how often they check their gas and they said every 3 weeks or so..
