more nitro rc help needed

[maverickxp]

OK so after a new engine and some modifications I got my ofna nitro RC car running and it was sweet. However I found out the hard way that they don't float very well LOL bit I cleaned her out and got the motor running again. Problem now is that my servos are screwy. The throttle glitches like crazy and if I try to turn it closes the throttle on its own and stalls. Any ideas? The servos work fine independently but when both hooked up to the junction box the problem occurs. Is that the most likely culpret. Thanks in advance guys
