Got some Denso 22s in now and car drives alot better but still has hesitation around 3000rpm to now 3750rpm on heavy throttle. Now being run on minimum 97ron all the time- normally sainsburys as it's 131.9 locally compared to local v-power of 136.9 or more. Anything I can be checking before taking it to a a garage? Breather system is clogged but I'll be removing old hoses and replacing with silicon ones to my catch tank tomorrow. Should there be a 1-way valve on crankcase breather port to catch tank? Also my fuel vapor canister has no vac line connected to inlet mani and I know FRS has one with 1-way valve on.
