High Co

[slow_matt 0]

Hi,

 

My pugs been off the road for the last two years, needed to shift it 40 miles today with no MOT and Tax, cheapest solution was to book an MOT and insure it for the day, obviously if it had past I would got the tax...

 

Well the test centre chap called and it failed on a few things, worn tyre, bit of welding and emissions too high, the first two things I can see so I know what needs doing, emissions however are a black art.

 

CO was 4.19% (max 3.5)

HC was 606ppm pass (max 1200)

 

The spec of the car roughly is 1988 1.9, K+N, XU10 head, Cat Cam, 4-1, magnex exhaust, flew through last time and nothing's changed.

 

It's lumpy runner, doesn't smoke at all, loves revs, hates low speeds.

 

Where's the best place to start with this?

 

Cheers

 

Matt

wind out the screw on the AFM, check the resistance of the ecu coolant temperature sender.

Take it for a few good blasts around (if you can) before going for the retest & if its still fails as above.

 

It might just need some italian tuning after being stood for so long.

Turn the Idle up, your allowed to do this on older cars anyway

Thanks for the replies,

 

Welshpug, cheers will have a look:)

 

There was 40 miles of that before hand, straight to the MOT, got a bit lost and ended up going on some backroads

 

The idle is already fairly quick, when it starts it sounds like a Harley, then 15 seconds later it gets into it's stride and idle's at about 1000rpm (though the rev counter is deaded...)

 

Cheers
