hackin_n_bashin Posted July 23, 2012 Share Posted July 23, 2012 It's more likely to be the coil pack clips, they're not expensive, and well worth changing as they break down and become brittle with age. Keron at extreme performance often has them, or try Paul at Wifbitz. Adam Quote Link to comment Share on other sites More sharing options...
crispy Posted July 23, 2012 Author Share Posted July 23, 2012 jody t has the car and hes saying its likey to be the coil packs as they were sat in water due to me buying a stupid carbon bonnet with reverse vents that let water all over the top of the engine !!!!!

Chris Wilson Posted July 24, 2012 Share Posted July 24, 2012 Seeing if a coil pack is misfiring is just a matter of scoping the primary and secondary waveforms, no need to buy, beg or borrow other ones. There's also a lot of misinformation about "coil pack clips". They DO NOT break down, they have no part in the ELECTRICAL connection, and are merely mechanical in nature. When broken they allow the spade terminals for the coil pack connections to waggle about, open up and no longer make a reliable connection. The spade terminals ideally want changing, for which Toyota sell a tailed repair kit, or carefully closing up to regain a tight fit on the coil pack terminals. if the plastic shells are broken these should also be replaced. With basic diagnostic gear you can tell in minutes if it's a fuel injection misfire or an ignition misfire, with virtually no dismantling (just 10 bolts on the coil pack cover....)
