Right I've had this fault intermittently for a little while now but it's just getting worse and worse.
A few weeks back my EML came on. I plugged in Peugeot planet and got a fault ' mixture regulation fault - upper stop'. Cleared the fault and it stayed a way for a while then came back and went a few times. During this time, there was no noticeable difference in power or running except for stalling occasionally when dropping to idle (my icv is mega f*cked)
Today it came on and stayed on but today I noticed a difference. It felt very sluggish. I pulled away from the lights and out it into second at 1500rpm and planted my foot. It climbed through the revs until I hit about 3500 and then it took off. It was like boost but really quite violent!
Light has gone out again but this still remains. I've done it several times now and same thing. Hits 3.5-4k and it takes off like a rocket!
My thinking was either MAP sensor (sticking st a certain value) or lambda sensor (I'm 99% sure my cat isn't working properly but I've had faulty lambadas before and they havent done this!). Lambda is only about 6 months old.
Just after some more input on this before I go spending or just scrap the bastard.
(it was good fun when it hit 3.5k though
)
