engine is hunting

[Madden]

need a bit of advice

My car is hunting but not on idle if you give it a little throttle and hold it at about 2000rpm the revs go up and down by 500rpm and the exhust note changes.   Any ideas?

Cheers jamie

[peterch]

don\'t know, is your\'e air con turned on,

[Madden]

no not at all mate no electrical load.   The exhust note sounds like its shooting a flame you know the noise as you lift of after giving it some down the motorway and give it atiny bit of throttle.

[peterch]

I know used to do the same, but it did stop on its own after a while.

Exhaust leak or faulty TPS may be

What mods are you running? :wiggle

[Madden]

The only mods im runing is a blizt cat back system still have orginal down pipe and cat but its slightly blowing before the cat at the joint. Standard air box i think the ecu has been played with as there is no speed limit or REV limit scary and it has a ks rom sticker on the front of it.  I have removed the double throttle since then the car has been playing up.

I am sure one or more of the tuners will post but i would advise that you give one of the supporting tuners above a ring. I had a problem with my fd early in my modding with hunting it turned out that it was down to after market ecu,not the Apexi i now have fitted, that was causing turbo spike to 1.1 bar and it damaged the side seals. Be careful and get some expert advice. HTH. :wave

Have just had the engine re-built by Geff @ RE:WORX. The standard port has not been touched as would seem by calling the engine street ported, as in enlargement, but the ports had been polished very nice job too. Geff has removed all the Hurley bits on my instruction. We will see what power we can make on the 27th Sept at RE:WORX Portsmouth on the Dyno. If you are free pop down. If not I will be at SantaPod on the 3rd Sept for the test and tune day where I will be going after the 1/4 mile British Record for Stock Twins. Sdminus -- holds it at the moment and he is going to try and join me so we can go head to head and push the envelope. :wave
