Misfire On Cyliner No.4 But Which One?

[voyager0uk]

hi all, we have an is200 2.0 which has been perfect till now, em light on and its shaking. we have put on an obd and got misfire on cyliner no.4. (changed plugs no change, think its the pencil coil)

question is... which is no.4? is it 4 up from the radiator end or is it the firing order (i have no idea what that is).

could anyone tell me which one to look at, counting from the rad end. thanks

You've had quite a few views and no replies, so I'll be the first to say sorry, I don't know. I'm assuming the others don't know either. I hope someone is able to help and that you get the car running properly again.

I don't know which cylinder is number 4 but the misfire will be a coil pack I reckon not a spark plug.

They normally fail in pairs as well so your prob gonna get another go down.

Member IanS200 had some for sale very cheap. Their about £100 each from lexus.

Another suggestion, take the coil of of what you think is cylinder 4. Swap it with another. Reset the ECU. Then read the code again and if the misfire has changed cylinders then you know which cylinder is which :)

its the 4th up from the radiator

I have some for sale as Chris says £10 each plus delivery.

3 are original denso other 3 are not oem but are a lot newer.

Coil 4 is paired with coil 3 so replacing as a pair would be sensible.

many, many thanks to all, i've been quoted £78 and £86, so went to good old eBay and ordered a new one - £35. I'll change the 4th one up and see how i go - best idea.

if i need one, how do i get one from IanS200 as i don't know my way around here yet and cant see a email or contact? cheers

hi again, just an update, got the eBay item next day, well happy with that, 4 plugs up and swapped coil over, started engine - perfect! so many thanks to all.

funny thing though - reset all codes, turned em light off, restarted car and em light back on. *remember to plug the air temp sensor lead back in first! Dohhhh

Good to know it was nice and simple!

Maybe post a link to the coil pack you bought, just so others looking to solve the same issue will have a port of call to buy one too - it's always useful to have a recommended seller/product from experience, than just hoping for the best

Congrats voyager. Glad it appeared to be a relatively easy fix.
