Idle and rev problem :-(
Hi not been on in a while
I have a 51 plate bug eye over the last few weeks i got stuck in stop start traffic now its been idling funny like ticking over at around 500rpm and sometimes drops right down to nearly 0 I have no engine lights on either . Was told try new plugs and fuel filter but no different (HELP PLEASE ) :-). |
Possibly the MAF needs a clean, is it remapped at all?
Also the ISV could be gummed up. |
I had this problem on my last scooby (blob wrx), I cleaned the idle control valve which cured the problem.
Hope this helps |
sounds like ICV
Either delete the water passage going through the throttle body which isnt need here as it dont get cold enough or by a new gasket before taking apart |
Not yet was told it might run poor as its had a walbro pump /up pipe / and a new k&n filter on a standard ecu . Will try clean them out tomora shall I just use like a carb cleaner spray ??

Ahh cheers guys will let u no how I get on once cleaned if not il replace . Now have engine light on being a dick I unplugged the icv with engine running n light stayed on . Luck next door has a snap on code reader . Just thought could a dodgy hks bov cause this ??

Hmmm, sounds interesting. I have recently put a walbro 255 on mine and its running really poo, everything standard on my car, but revs hunting and dropping down to zero when approaching traffic lights as I dip the clutch to stop. Never did it with the standard one.I've been pointed in the direction of my MAF which is a poss as its 13 years old but your the third person that has a walbro on then had issues???
As for the BoV I had a similar prob with my Forge one. Each time I stopped and dipped the clutch pedal the revs fell and the car nearly stalled, took it off put the original recirc back on and the problem went away. |
Yeah the hks bov somtimes don't dump like its ment to . As for the pump now been told walbro use a smaller sock reducing the flow more than a standard ?? Gonna clean the icv and see then if not may just drop it into slowboy racing cheers for help and comment tho

alot have said about the icv so try both! |
I have a receipt for it from scooby world . Yeah a few mates have had a few wrong uns . Yeah gonna try again tomora hopefully will get it sorted . Another question can the ecu be reset by hand or only a computer ?
|
You can reset by hand using the test connectors under the dash, I think JGM has instructions on his site.
If you clean the ISV make sure you get a new gasket first as you'll never get the old one back in! |
Afternoon guys just have the bug eye code read again after trying to clean the icv but with no luck . Again no faults found he seems to think i have a air leak somewhere are there any common pipes that go ? Its still hitting around a bar of boost tho with no problems ?
|
Sorry lads only me again . There is a electronic valve ? On the passenger side of the engine beside the washer bottle with around a 3 inch hose coming of it . Dose anyone no what this is or weather it's meant to be connected to anything??
