Armie New Member 12 Member For: 12y 6m 5d Posted 24/08/14 10:14 AM Share Posted 24/08/14 10:14 AM Please tell me you've gapped the plugs! I know it sounds obvious and maybe not relevant but mine had been running rough for probably a solid year, had the return line drilled out at the fuel pump but still ran rough, checked it on the dyno for ratios etc etc, the plugs I'd fitted two weeks earlier still factory gapped so a 20 minute job to gap em smaller and I'm running spot on, still a little rough on dead cold unless I let it idle for a few minutes.

MADD Matt New Member 1 Member For: 7y 6m 26d Posted 19/06/19 04:34 AM Share Posted 19/06/19 04:34 AM Another pump question. BF xr6t - flash tuned and flowed injectors only (stock pump). After sitting for a couple of hours when starting you need to hold the key on for a few seconds before starting. Strait starting results in pre-ignition or backfire (which blows the PCV hose off). 1: Is this likley to be caused by fuel pressure dissipating when shut down? 2: If yes, are there a few likely causes. I can buy a guage and test but if there are other ways to diagnose the prob with my eyes, or if there is a common fault peeps know about I can save the money.
