Hesitation killing my will to live

[ExiledWeegie]

the ones in there are NGK Platinums PRF6Q,, its got to be running a bit rich with the black plugs, the unburnt fuel burbling in the exhaust when off throttle and the LTFT having to lean out the mixture a bit, I know obviously its still within tolerance but it could be a bit lower than -6.2% thats its now sitting at.

Found this Beru document I had on my laptop

according to that document its Cold/Carbon Fouling, when I run my finger round the plug its comes off as black soot.

got the new BKR7E plugs, still waiting on injectors and a feeler gauge, cant find the one I had and I dont trust the little round gap tool I have.

got the BKR7E plugs, gapped to 0.028 and put them in, the misfires on full boost are gone and no codes so thats a win, still hesitation though sometimes before boost comes in and then sometimes when boost is in, injectors should come tomorrow and i bought an inlet manifold gasket so going to do both together, if that doesnt cure this I seriously dont know where else to go with it.

Fingers crossed for you

Fingers crossed for you

well thats the inlet manifold gasket done and 4 Bosch injectors in it, reset the ecu with battery off for 30 mins and took it for a 5 mile run, seems to be running good, didnt really give it any beans yet, time will tell now, im taking it for 15 mile run tonight so that should show more. cross your toes as well please, i need all the luck i can get with this thing

Toes crossed en buttcheeks clamped with 100Nm force, check

that was 20 miles done tonight, maybe a bit more, plus the 5 earlier today, car seems to be running good, I couldnt really open it up as the wife and son were with me but I monitored the fuel trims from setting off, got home and the LTFT is -0.8% so massive difference, those cheapo injectors mustve been pissing fuel through. tomorrow I'll open it up a bit and see if all the hesitation is gone but first impressions seem good.

Good preliminary results, lets hope it solved for good now Seems like 100Nm buttcheek clamping force is the sweet spot
