any ideas on whats up with my mk1 anyone? when warmed up the car ticks over at around 800rpm but recently after it's warmed up it's ticked over at 800rpm then it starts to drop and become uneven till eventually it goes below 500rpm and stalls.
someone mentioned to me that it could be the auto choke but can't see why this would make it tick over like that?
On Ford Kas this is generally the idle control valve. The solution is a new one or liberal application of carb cleaner.
over at around 800rpm but
drop and become uneven
this would make it tick
Your MK1 what ? MR2 iirc ?
It's fuel injected, so doesn't have a choke. Best to find a verifiable expert on your particular injection system who can do a correct diagnosis first time and repalce the missing part. It could be any one of a number of things.

would make it tick
You may have an idle adjustment screw some where that has slipped out of whack, or possibly a fault with one of the sensors that report to the ECU though that normally ups the tickover.
In article , blank@128.0.0.1 spouted forth into uk.rec.cars.modifications...
Sounds right. Even sometimes dirty conections on the Lambda sensor can do that, because it reads the gasses and passes wrong information.
ah cheers people i think it's me idle valve or a sensor, will check tomz...
Lambda doesn't start operating till the car is hot...
Hmm, true. Probabley either the cold start valve (whatever form it has) or air metering then.

Clean out the jets in the carb.
My Capri did this this afternoon and all I did was clean out the jets, probably because I forgot how inaccurate Capri fuel gauges are and sucked through a load of s**te from the bottom of the tank..
Ah, the joys of ancient engineering. 5 minutes with a screwdriver and job done..

Oh.. you use that newfangled Injection stuff don't ya? You had me confuddled with mentions of Auto Chokes....
Until the sensor is, you mean. I don't know if the MR2 has a heated sensor, but our Ka does.
