Car question sorry! 323 feels like its going to stall

[wizzzard]

I went to collect one of my bikes from the bosses garage last night and I drove there without a problem. My wife drove back and within half a mile the car had started chugging when coming up to lights. I caught up and followed and it seems to run fine at speed but whenever she came to a stop or slowed down to a crawl the car would shudder and chug like it was about to stall although it doesnt actually stall.

I know the obvious answer is not to slow for anything

The car is a 96 mazda 323f and I was wondering if anyone could give me a few pointers on where to begin looking when I get in this evening.

Idle control valve dirty? How is it on tickover?

It's hunting on tickover. Sounds like the exhust is blowing when you pull away but that vanishes at above about twenty.

Thanks Finglonga. Will check the idle control and I'm going to check there are no perished pipes.

Blocked injector(s)?

[wizzzard]

Thanks Phoenix I've been looking around on the net for ideas and hadn't come across that one. It does sound like a possibility but the car itself isn't worth the price of fixing that so if it is the car goes in the bin.

Now to find out how to test for a blocked injector

No management light on and the blowing sound is coming from the end of the exhaust no holes along it or anything but it just sounds just like it would do from a hole along the pipe.

had a similar problem on a rs2000, if the idle is hunting, the valve appears to be working. Most likely a air leak in the inlet manifold. with the engne idlng, spray WD40 around the inlet manifold everywhere from the airflow sensor to the block. the blowing sound is more likely a sound similar to an induction kit on performance cars. a blowin exhaust sounds wore the faster you rev, an intake leak gets quieter, as the ratio of air thats leaking lowers compared to the metered air.

PS the rs2000 had a vacumn hose that had fell off!! took us bout 4 hours tofind it!

It turns out it was indeed the idle control valve, thanks again Finglonga.

Tried cleaning it to no avail so I've unplugged it and it now idles without stalling but has brought a flashing hold light up on the dash. The car seems to drive absolutely fine again now with the only exeption being that it seems to stay in gear longer before changing up ( its an automatic so sounds like im reving the nuts off it at low speeds ).

The car itself isn't worth getting a new part for and ill just get a new one at the end of the month but was wondering if this one is ok for my wife to drive in the mean time.

I had some Maplins electrical solvent cleaner around so I tried that. I was a little unsure how harsh a product to use.

Hi

Carb cleaner is probably the best thing to use.

All the best

get some engine cleaner and shove it in your tank ( not redex.. proper stuff.. ).. take the car for a nice long drive and should see a marked improvement..

if im right the mazda's have the same engines as the fords didn before zetec and they had the same problem..

it stems from using cheaper fuel like supermarket fuel.. once its unbloked every 4th fill up use the expensive petrol and should be reet.
