1.6 performance / pinking / revs not dropping off

[oldbury863]

Hi, I'm new to this forum but I'm hoping someone can shed some light on the symptoms I have with my 2002 1.6 focus.

1. When it's cold, the car goes really well, but when its fully warmed up, it definately seems to require a heavier right foot to make it go & has a bit of a flat spot.

2. It's also prone to pinking when pulling away.

3. The engine revs take too long to drop off when changing gear. This causes the revs to surge slightly when I drop the clutch.

I think it might be an emmissions problem, or maybe the mixture is generally running a bit weak.(?) I cant find any obvious split pipes & I've looked through the haynes book, but didnt find that very helpful at all. It tells you how to remove things, but not really why you might want to in the first place!

I've heard mention of MAF sensors needing a clean but the 1.6 engine doesn't seem to have one at all (?!) If it does, it certainly isnt next to the air cleaner where the 1.8/2.0 engine one is.

Any help would be very much appreciated!

Sounds like an air leak to me?

Sonds exhaust related. Ai leak would lead it to bearly runing or trying to keep it slf level. I would start by checkng o2 sensors, your evap system, thing lke that. Let us know what happens.

Thanks for the ideas, I'll take another look at the weekend & keep you posted. . . . . .
