    Engine Feels Gutless At Cold

    Hey guys, my mk4 1.8 16v feels really gutless when its cold, reversing off of the drive or just setting off in first gear can prove tricky.

    The engine feels like its going to stall....at which point you dip the clutch and the engine is at around 500-600rpm and the car is shaking. Sometimes giving it some gas will bring the revs up and it settles at idle again, but if you dont get quite a few revs on the engine goes and does it again.
    Up to the point of almost reaching operating temperature.
    But even at operating temp.....the revs drop when you come to put it in 1st gear at a junction, the car shakes a little....and the engine revs pick back up.
    I was going to clean the ICV valve out, but it doesnt appear to have a ICV.....so im a little stuck as to where to go now.
    Anyone got any ideas?

    Im not too sure which engine i have, so i have included some pics from under the bonnet.

    could be your EGR valve that needs a clean.

    i believe your eninge is the X18XE1 in which case it should have an EGR valve although not 1.8s do (although i think thats only the Z18's)

    Ive already seen the EGR Valve on it

    Thnx for the responce guys, is there a gasket between the EGR valve and the bracket it bolts to?
    And if so will it need replacing once the EGR has been removed to be cleaned?

    There is a gasket yer, it's a metal one, I spose it'd be advisable to replace, but when I took mine off to clean it I just re-used the gasket.

    My car is quite often sluggish when cold, but I put it down to the engine needing to warm up, try leaving it to idle for a few mins before setting off, and don't take it past about 3k-3.5k rpm. Once it's warm it goes much better.

    When was the oil last changed btw?

    Cheers for reply jace, the car isnt so much sluggish.

    Just that it feels like it wants to stall at any chance it gets.

    Setting off at cold requires 2000+rpm.....setting off at warm can be done at 1600-1700rpm.
    If you dont get it right at cold, the engine gets really upset and starts stammering.
    Also would mention.....blipping the throttle once or twice at cold is sufficient to stall the engine sometimes.

    No EM lights popping up.

    Oil was done August last year along with new front tyres.....plugs.......filter etc etc.....checked the plugs, they look new. It had Duckhams 10W-40 Semi Synthetic in.

    I have a similar thing where it stalls just from blipping, I would wager the Air Flow Meter being responsible. I just haven't been bothered to sort it out yet - I'm too lazy!

    I have the same engine, I would definitely say it helps to let the engine warm, even if its for 2mins, when I am running late in the mornings and drive straight off after starting it definitely feels shite.

    You might want to give the throttle body a good clean out as well.

    LOL, dont really want to replace the airflow meter until it goes completely boobs up!

    About 2mins after the engines been running, blip the throttle the engine becomes more responsive...and revs up quicker and just settles to idle again.
    Doesnt do it while being warm.
