Hey fellowz..woundering if u can help me out..got dis massive problem with my 4th gen vtir lude. The problem is my car keeps on reving up and down on idle by it self, from say about 800-1300revs continously. Just up & down & up & down. My mate said it might be my injectors are dirty so petrol dosent go down probably. Ive just recently changed my fuel filter. If any one out dare can help it would be great..thanks guyz.=]
check your ecu codes,see if its throwing any codes out.
engine running rich and [acronym:36871af103="Idle Air Control Valve"]IACV[/acronym:36871af103] are the most common culprits, like handa_b_blastn said you need to check the ecu for codes,
Bad [acronym:7d80edf179="Idle Air Control Valve"]IACV[/acronym:7d80edf179], Air bubbles in coolant, Vaccum Leak - Check all hoses etc.. u might of knocked a small hose off when you were changing your fuel filter and also try resetting your [acronym:7d80edf179="Engine Control Unit"]ECU[/acronym:7d80edf179].
or like me rotar comes off in destributar making it run like shit
How do u reset ur [acronym:03489af414="Engine Control Unit"]ECU[/acronym:03489af414]? n check for codes?
Take your battery cable out for 30 mins that will reset your [acronym:d32943aa1c="Engine Control Unit"]ECU[/acronym:d32943aa1c]...
actually 30 sec will do it.Quote:

good luck
what these guys are saying is absolutly correct, check all these things. I had the same problem and it was a dirty [acronym:165632dec0="Idle Air Control Valve"]IACV[/acronym:165632dec0] , go look in the DIY section for how to clean it.
Normally, it is the sensor problem or ecu. Go to honda dealer. They will tell you how to do. Good luck!!
99% it's the Idle Control Valve as the others have said.
sounds like ur idle's hunting, just check the following:
-vaccum leak or air intake leak
-valve settings(need adjusting)
-distributer caps gone
-might new spark plugs
-leaking or dirty injectors
- idle control valve
Hey fellaz, thanks for all your help, the problem was the idel control valve. I opened it up and gave it a good clean and now everything runs as good as new.
cheers fellaz!!! and thanks again=]
