My engine is still runningvery rich (6.9% co) which is causing a misfire.
I have tried pugs and leads dizzy cap and rotor arm coil,before I got the gas analizer out and found how rich its running .
Since I have changed the blue temp sensor,02 sensorand the co potentiometer and no change
have i missed something ???
also I can pull off the vaccum hose to the ecu when the car is running and no change, this can't be normal so I would guess the map sensor is screwed?? If so can it be changed or am I looking for a new ecu
thankyou in advance

Re: What else can I try (leeG)

maybe the fuel pressure regulator, or stuck injector could be the culprit. Its easier to swap(borrow) an ecu to try, imo.
Make sure the vacuum hose to the ecu goes to the right nipple on the TB

I got my money on the Vacume line for ECU on the wrong nipple of throtlebody!

could be many many things but I agree there are vacume line issues if everything has been replaced, but don't rule out something you have replaced as you can get bad parts

ECU plugs into the passengerside port

I'm still a bit confused?? there are only 2 nipples on the back of the TB? I have the ecu hose in the top one, the other is blanked off because I have MK1 clocks
thanks again
