Stock fuel injectors, UK

[Alan_C]

Does anyone know a source of stock fuel injectors in the UK?

Seems one of mine (no. 4) goes intermittant. When starting the car from cold, should it misfire and doesn't catch, turning the ignition key a second time to attempt to restart, it will require longer than usual before it finally fires. When it does fire it's only on 3 cylinders. Pulling the plug leads points to no. 4 cylinder not running, there's a good spark there. Removing the plugs shows no. 4 very sooty. Replace the plug with one from another cylinder, and no. 4 is still not firing (these are NGK iridium plugs gapped at 0.8mm). Attempting to drive the car, as you'd expect it's lumpy, but when boost is reached, the fault clears and the engine runs clean, back to tickover and it's lumpy again. Do this a few times, and eventually it will tickover on all 4 cylinders. My thoughts are it's a sticky injector, so no. 4 is running far too rich, backed up with a strong fuel smell from the exhaust. Strange thing is if it doesn't misfire on the first starting attempt, it'll fun fine from cold. Could be just that on occasions that injector is sticking open causing the starting misfire? Either way, I need to swap the injector, I could move it say to no. 1 cylinder and see if the fault moves with it, but as they're a right bother to remove, I'd rather replace with a known good one, but can't find a supplier in the UK. I've read that R C Engineering are a US source, but changing just 1 injector will give me an imbalanced set, as theirs are not exactly the same as the factory fitted items?

You're right about the RC injectors being diferent from the stock ones. They have a different pattern. As I understand injectors, the are superior to the stock paattern. If you don't use your car as your daily driver, you can send off the bad injector to be rebuilt. It's inexpensive, and I'm sure there are plenty of places there to do it.
