We've just acquired a second ZX, this one for me, to replace the C-15
I used for work (an amazing car in itself, over 370,000 km on it,
drives like a gem, though I'm pretty sure the engine was replaced at
This ZX is from 1992, and has the 1.6 injected engine.
It's in overall very good condition, except for this occasional
Here are all the details; I hope someone can point me to solving this.
The stalling started gradually (hardly once on my first drives) and
worsened this past week (the previous owner said he felt it just once
prior to the sell. I believe him).
The stall happens usually around 2500 rpm, and feels as if something
cuts off the fuel supply for a split second (which I won't be
surprised if that's exactly what's going on).
It comes at random, sometimes hardly shows at all, but as it has
worsened these past few days, it can come in very short intervals,
repetetive, when it can feel like the engine might totally cut out
It usually happens when the engine is cold, or coldish, and I don't
think it ever happened when the temp was over 90 degrees.
It will stall more in steady state driving (around the 2500 rpm) than
If you go over the 2500 mark, the stall will usually go away.
What was done so far by the mechanics was a combo of gas/ignition
stuff, beginning with the more basic/simple/cheap:
Change of the gas filter,
Change of the spark/ignition cables,
Cleaning of the main(?) gas injection housing(?) and of the "step/
distribution" motor inside it Change of the ignition distribution/
Bottom line, none of the above solved the problem (however, what seems
very strange to me is that after some of the above treatments, the
stall stopped for a while).
Anyone encountered such a thing?
If it is indeed a gas issue, how does one proceed?
Gas pump? Something else along the gas-line to clean and "free"?
Thanks in advance,
