Hi forum, been reading loads, finally registered to ask a question
I've got a 99 Zafira 1.6 16v, think its the Z16XE engine. 61k miles.
Had the car for over 2 years now and everything been great. New battery about 6months ago, and a new alternator about 5months. The other day it started to stutter on accerelation. There is never any light on dash to indicate there is a problem. It goes like this:
Start up is great, first turn of the key etc. and it ticks over fine at about 1k for a bit then drops to a steady 750. You can rev the engine fine without load, but if u but your foot down, it misfires and stutters, then it revs fine. If you do it a gradual rev, it sounds and feels fine.
While driving, again, pulling off is fine, but if you put your footdown it stutters, more so when in higher gear (assume more load). If you back your foot off the accerelator pedal, it seems to surge forward and catches up. The revs still climb while it stuttering, like a bag of nails. So you do go faster, just slowly and not smoothly.
I've started cycling to work a few days to work, so car is left much more then it's used to. I also put about 10 quid of asda petrol in last week (last time i put some in).
So far i've:
Cleaned out the EGR, what is the best way to test it? the plunger was in the hole and it had a lot of crap in there. It made a bit of a difference. I also sprayed a load of carb cleaner into the throttle housing. This again made a bit of a difference. I also just feeled it up with BP ultimate, incase the fuel was crap. Again a little difference. I keep reading about cleaning out the ICV, but for the life of me I can't find one on my car, or find it in any pictures in the haynes manual.
Not sure where to go now, whether to wait a week, to see if the fuel clears itself, or try possibly a new EGR or a coil pack thing.
Suppose i'd like to know where the clever money is, a new EGR or Coil pack thing.
Thanks, any advice be much appreciated!
(my steering controls also have stopped working, since i replaced the battery - no idea why, but that aint important right now)
