Hey guys i just picked my car up from the machanics were it had just got new splitfire coils nd plugs put in nd on the drive home i was testing it out nd all of a suddend it started sounding real rough nd has no power now. almost sounds like a wrx but with no power

Can any1 give me any ideas 2 wat might of happend?

Time to learn how to change coil packs yourself. You'll need 2 hands, a socket set and a set of hex keys. Go get 'em cowboy/cowgirl.

No seriously....the mechanic didn't put them on properly. Either a plug has fallen off a coilpack, the coilpack isn't seated onto the plug properly or the screws are missing from the coilpack brackets. Many mechanics are so hopeless it could be all 3.

You will work it out by taking it apart and putting it back together. The coilpacks are under the cover in between the cam covers, under the cross-over intake pipe. Yes, you have to remove the cross-over pipe, then it is plain sailing. You do not have to remove the spark plugs. Make it a game and time yourself. If you do it in less than 60mins your GF owes you a blowey.

Take car back to mechanics?

If you want to do it yourself, remove the valley cover...then put the pipes back together so you can start it up again. While idling, remove and replace each coilpack loom plug...one at a time...until you get to a coilpack that makes no difference to how the car sounds. This is your non-firing cylinder. Try swapping that coilpack with another healthy coilpack, and see if the non-firing cylinder has changed places or stayed in the same spot. If the problem follows that coilpack to the other cylinder, then faulty coilpack...if the problems stays at the same cylinder then it could be a faulty spark plug or coilpack loom plug.

My car done this with brand new coils. One of the coils died. Then they all died. New set works brilliantly. One of your cylinders isn't sparking. Unplug each coil one by one with the engine running to see which one does not make it run worse. When you unplug one and you don't notice a change, you know that cylinder setup is f**ked.

Probably not what mine was, but after i replaced my ecu i found the connection wasnt the best and was causing this exact same thing. I also had the same thing happen when i replaced my coil packs, and in a hurry forgot to clip number 6 back in!

Oh yeah, and definately do ur plugs and coil packs ur self from now on- you wouldnt believe how easy it is. Im not the most mechanically minded person and it takes me less than half an hour to pull out gap and replace all my plugs.. not worth paying someone else for it, especially since they got it wrong

Check if the ground for the ignitor pack is properly on . And if it starts doing it while it gets hotter its most likely the ignitor module. Try using a spray like contact cleaner and spray it on the ignitor while the car is running as the contact cleaner will cool the igniter down very quickly and your revs might stabilise. Thats what happened to my car , had to get a ignitor from the wreckers , and problem solved. Wish i knew that before i changed to another set of Splitfires and new plugs..

This problem occurs mostly with CA's because theyre so old now , so I guess since RB's are getting older this is going to start happening to them aswell.

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
