Took the car to MOT station this morning, its the first time the car has been driven in 6 months. Drove the 8 miles there, but when you came up to a junction or round about and slowed to idle it was pretty high andwanted to keep going in gear. Then when the car was on the ramp getting tested the engine started hunting, it was blowing out some white smoke from the exhaust but it was pretty cold, then when it started hunting the smoke disapeared. The car failed on emissions, the Co2 was 6.50 when the max for the test was 3.50 The tester thought that due to me running it on optimax, that may be the problem. Anyone else had simillar or have any ideas???

Car is a 1990 S2.

Auxiliary air device may be sticking open, and obviously the emissions need playing with aswell.

If its been sat for as long as you say it could be a number of niggly little things

 

Thanks for your post mate

Auxillary air device, what the hell does that do, where does it live and how can i check to see if its okay or not???

Hope there arent too many niggly wee things, as it did okay for its test!!

Its down underneath the inlet manifold.

Follow the hard plastic pipe from the throttle housing and you will see it.

It has an internal heater which warms a bi-metallic strip and closes up over a period of about 2 minutes to allow a little more air into the engine while its stone cold.

Check the wiring plug is connected and you could remove it and check to see if it closes up with 12v across its terminals although they can be a pain to remove.

 

easiest to remove from underneath!

 

Ah right okay, well the car is on the garage now, and im away offshore on monday for a few weeks, so ill get onto that when i get home.

Thanks for the suggestions there guys. Hopefully something simple like that or maybe just a case of needing set up correctly!!

Cheers,

Neil

You never know the garage may find it out and sort it before im home!!
