RUNNING ISSUES after engine work!
Hi Guys, in the shit and stuck on what to do!
car running hdev stage 2a chip, 555 nismo's and all relevant mods
story so far....
s14a went in for new gt28r turbo swap and to solve comman oil leak on head. ended up be recommended head gasket to be done to fully solve leak, once head was taken off the inside was dry and caked in burnt oil, as no compression test was done before head was taken off piston rings couldnt have been ruled out!
so work carried out as follows:
#head-new stem seals, head skimmed, valve seats honed, new bc valve guides
#main block-bores honed, new oem pistons rings, all new bearings, oem timing chain kit,new thermostat
#other bits- new 28r, h-dev stainless mani (2nd hand but in good nik, ) lamba sensor
engine was put back together, was told it was ticking over fine (so i was told!) for 10min or so till the car ran out of fuel (i had told them it was low, forgot to fuel up before i dropped it off to them) i had dropped of a large jerry can of costco 99ron fuel. they topped it up and she wouldnt fire!
they checked everything, fuel getting through, filter etc etc, they then said the fuel was duff and seemed more like fuel'y water!!! i suspect someone at the garage has nicked the fuel, either way cant prove it!
they checked everything, drained the tank and put new fuel in.
she fired up but was rough and seemed to be misfiring on throttle, they again went over everything, still missing but they blocked the fuel regulator that stopped the misfire/power drop at higher rpm throttle but lower still is shit (same noise and running as if fooked coilpack) they verdict is it needs remapping!!
now my mate and i have tried everything under the sun today to fix it! different plugs, coilpacks (running vag con. ), even tried brand new walbro 255 fuel pump!
tried everything we can think off.....only thing now is timing! noticed the cas sensor is on its max posistion.
basicly any idea's??????
(just to rub salt into the wounds it failed mot today )
