Car issues ahoy!
Discussion
Hi chaps, I've unfortunately got a few problems at the moment that I'm hoping I can have some help with to fix.
1: I fitted a new 4-2-1 exhaust. I previously had the standard single piped Caterham example. My problem is that the exhaust sounds odd when driving. I liken it to having a playing card in your bikes spokes, and then spinning the wheel. This only occurs when the accelerator is pressed.
I'll try post up a sound clip as it's hard to describe.
2: My idle is up the swan. I'm having to rev it at junctions to prevent it from stalling. This problem only occurs when at very low revs e.g. sitting at tick over, creeping up to a junction.
It'll go from 1000 RPM steady, then blip to nothing then back again. The engine has to catch it's self to prevent stalling. But at times it'll stall when the revs drop.
It happened to me today while pulled over in a lay by. Not a big issue.
It also happened on the way home mid roundabout due to some ill positioned traffic lights causing traffic to stop on it.
3: Last but not least. My car is deciding not to start at every turn of the key either (e.g. when stalled on the roundabout mentioned previously!). The lights work still, so I'm still getting power. Turn the key and I get a click but nothing more.
I've recently put a new battery in and positive lead to the starter motor. If the starter motor engages, it starts first time.
I don't think it's the battery at fault, neither the connection as I can park the car. Turn off the car, start it back up again to check all's well. Then come back to it after a short while, to find it then won't start.
I'm thinking the 'dreaded click of death/ doom/ annoyance', but it often won't start when cold, so it's not isolated to when hot. I though that was a characteristic?

Cant comment on 1 & 2 but 3 sounds like the click, easily fixed with a relay from Halfords some wire & 15 minutes of time, check the 7FAQs on Blat Chat for the How To guide.
I had starting issues a while back which turned out to be a bad connection on the positive lead to the starter motor. In the mean time, I bought the items mentioned in the FAQ but never fitted due to sorting the problem. I also thought that I'd leave well alone once it was working. Knowing my luck I'd cause more issues!On that note, I never bought any wire for the job. Do I need to use specific stuff? I'm guessing anything suitable for a house won't do?

IIRC you need a length from one of the relay terminals to the solenoid?
The 'problem' sometimes appears to sort itself, it will be back if it's the click!
1,2 could be the Lambda sensor, if your car has one. Was it on Cyl 4 and you've moved it down the pipe, or up the pipe, or from the Cataclysmic Perverter to Cyl 4?
If answer to ANY of those is a Yes, you could consider trying to pip imoboliser On, then turn key on (but not engage starter). Push accelerator in/out 5 times, then turn off and pip imoboliser.
I've had 2 several times putting on/watching fall off CP and had to do this. If you've not got an Emerald (E.G. MBE, etc) you really may have to do this.
Just a thought for what it's worth is an easy fix/try!

I've put the lambda sensor back in primary 4 as there was a boss for it. Could this have got damaged during the change over? Anyway to check?If answer to ANY of those is a Yes, you could consider trying to pip imoboliser On, then turn key on (but not engage starter).

I've tried the resetting procedure, but it's never got any better. I don't hear anything happen after 'resetting' though. Should there be an obvious sign? I've always none the wiser.
Right, I've just carried out the 'Relay Mod'. Lets hope that this sorts out my starting issues.
I still have a rough idle. Car idles at 1500RPM dropping to 0. The engine normally catches and doesn't stall, but not always.
I'm thinking either the Lambda sensor or Idle Air Control Valve (IACV) could be at fault.
The lambda sensor I swapped over from the old exhaust to the knew, so I have put my jinxed hands on it.
The IACV just sounds like it should be at fault!?
If I can find a local K series Caterham owner to me, can I swap these things over and see if my car runs better, or is this not likely?

1. Could be poor seal of the primaries to the head - did you fit a new exhaust gasket? I was next to a Duratec car at Goodwood on Saturday that made the noise you describe and it was due to a poorly fitting gasket.
Hope the exhaust is OK otherwise.
I think you were bang on. Just fitted a new gasket and appears to be fine. I've only been on a short run due to the time and weather, but all seems better.Hope the exhaust is OK otherwise.
Thanks.
