On start up smells of petrol a lot from exhaust, it uses more petrol than my type RA, the my93 is standardish running about 240 bhp, and the RA is running 300bhp+ so seems fishy to me!, slight blue smoke on start up, but none when running/hot, but exhaust gases still smell too much of petrol, any ides please people? thanks

I will also add that it is very occasionally throwing up a cel, during normal driving, sometimes does sometimes doesnt, it will only stay on for less than a minute, and will also dissapear when i take the revs below 1500, any ideas please? could a sensor be naffed? lambda meybe?

Lambda, coolant temp sensor or MAF all contribute to fuleling, if any1 should fail this can cause over fuel. Personally id go for coolant temp sensor 1st, this is the most common fault for overfuelling in my experience.

do a code check but i would say maf or temp coolant sensor !

Due to the age of the car, it could also be the pressure regulator. When I had a power fc fitted and mapped to mine (also a my93) the mapper commented on how rich it was running, however due to your car occasionally throwing a cel, I would do a search on the code to see what it is

thanks for the replies all, how do i get a code from the cel, is it by connecting the leads under the steering column etc etc?

connect both blacks and turn on ignition and watch and count the cel light flash !
