Hello all I'm searching for help to solve my very agravating problem. Bad idle and running conditions. I just installed a bunch of new parts and it ran fine before but now its really crappy!
Here is what I had before:
94' S13 blacktopz32 mafstock internals & turboGreddy VSPL FMICBlitz Access tune ecuapexi SAFC II255 Walbro fuel pump370cc injectors
All this ran fine untill I installed all my new goodies and I'm completly baffled at what to do next ....please don't flame me I'm very very stumped at this point.
New set up:
94' s13 blacktopHKS 264 Step 1 in/ex camsGreddy valve springsGreddy 1.2mm head gasketMegan racing exhaust manafold with elbowApexi Power-FC with commander and optional boost control kitGreddy oil filter relocation kit550cc injectors255 Walbro fuel pump
Ok this is what I have set so far on the Power FC:The MAF is set to VG30 for the z32 maf and that is it so far. I don't have a fuel pressure regulator because I was told I wouldn't need one untill I upgraded to the 550cc injectors.
The car starts and runs but only assisted. If I took my foot off the pedal it will die. I checked the plugs and they are all dry but carbon deposits on new plugs so that tells me that I'm running very very rich. It runs very good at 3-4grand with proper vacume presser. When I let it down to around 1100rpm it gets very very lumpy like its running super large cams. I thought these 264 cams were not supposed to mess with the idle this much?
I set the valve timing just like the service manual said by setting the ex cam at 12oclock and the in cam at 10oclock and crank at TDC. Then I installed the CAS just like its supposed to with the yellow dot lining up with the notch.So my questions are:
What is the vacume presser supposed to be with HKS 264 step 1 cams?Does anyone have any clue as to what settings I should run?Can the richness cause the idleing problem?
Sorry if I confuse anyone It's almost midnight and I've been working on this problem for about 8hrs now.....
Please help
