My car failed MOT, bugger!

[DeLorean Cars]

- Primary pressure was tested and set to the correct specs

Correct for what? The camshafts and the compression are different on the DeLorean than the engine they were designed for.

The bottom line is that you can tune it in while at idle, but it runs lean in the rev range - therefore increase primary pressure to steepen the AFR curve.

UNLESS the problem is ignition. What coil are you running? There's been quite a bit of discussion on DMCTalk regarding the use of "performance" coils and it has been proven that the ignition amplifier is designed for the stock coil, via the resistors and anything else can cause trouble.

Are there any vacuum lines that could be wrong and preventing the correct enrichment?

You should run your stock 066 CPR and plumb it in to enrich under throttle deflection all the time. The 038 (Volvo) CPR does very little on the enrichment side and no working CPR action would cause what you see.

There you go James, Martin should be able to sort it out for you
Does he live near you?

Martin,

It was set to the K-Jetronic parameters as laid out in the manual, it cant be ignition if richening the mixture solves the issue, but James had issues with the running before he fitted the Volvo gear IIRC.

If we ask Dan Stacey nicely he might bring his fully tested Volvo gear, we could fit that on at Eurotec and see what we get?

I will do my best to squeeze my volvo gear into my car for you james. its the whole system complete with volvo cpr, nick T shimmed and tested and CO set.

I have a spare oem spark distributor too, I will pop it in the car just in case if I remember

Coil & Resistor
Has anyone got a stock coil and ballast resistor set? mine is not OEM, it was changed ages ago for somthing different which required a change of the balast resistors from a pair of resistors to a single one.
I think it came from Hervey when I was chasing a promblem many years back, if its a potential problem then I should eliminate it.
I'll have a check on Sunday if I have the balast resistors and OEM coil on the shelf somewhere.

MOT permitting, I'll be up on Thursday night so I'm there all day on Friday, when do you arrive Nick? I'm consious that you get very busy and my can will require a bit of time spending on it.

Handbrake
Any quick tips on how to get the best from the hand brake, the pads are in good shape, should I just tighten it up as much as possible.

Right so the car is booked in for its MOT tomorrow, I dissasembled and rebuilt both rear parking brakes and now they are performing much better than previously. headlight adjusted, fog light fixed, mixture tweeked. fingers crossed!

Yeah maybe, I've never had any trouble with the local place but I didn't recognise the name on the certificate so perhaps it's a new chap they have working there.

See what happens, if all else fails I'll just drive up in my normal car, not the end of the world.
