Hesitation at 3k

[Paul_13]

I know this is the change over in the injectors from pre ignition, but it's quite a pronounced hesitation/lack of power for a split second and feels like it almost wants to cut out. 

Is it just a case of knackered injectors or something else that's at fault ? FPR is reading as it should on PP2K  

[Poodle]

Sounds a bit odd, certainly not normal, no idea what could cause it though.

[JTaylor2005]

Opposite of VTEC???

[Piggy]

have you not just had astg2 remap fella??

not a coincidence?!

[Paul_13]

Yes, but it's been there all along

Nothing to do with the map.

[Uberderv]

Can you check fuel pressure on pp2k, actual against requested?

[Paul_13]

Yep, seems to be good

[Poodle]

All the air doser and egr stuff removed?

[Paul_13]

Yep egr blanked and removed from map.
All alloy inlet elbow so no air doser

[Toms306]

Is it anything to do with the 3rd piston in the pump? Can't remember when that usually cuts.

[Paul_13]

Ah yes, sorry this is my memory failing me. You're right, mine was being a pain and playing up

[Poodle]

Unplugged?

[Paul_13]

It's unplugged now about to take it for a drive

Still there, not as pronounced

I think there's an issue with the pump. I'm going to stick the r70 on and the 1800 bar sensor

[Uberderv]

You can just Wang the pump on first. Once the sensor goes on I think the map has to be calibrated to match its new output.

[Poodle]

Indeed, two of the wires on the sensor need swapping too.
