Can anyone please help me?
My car coughs and splutters when i start it cold, then the auto choke comes in. When i drive off when its still cold the engine hesitates and coughs, i put my foot down and nothing happens, it splutters its way up the revs then at about 3500 RPM it comes right. The engine is totally fine when it reaches operating temp, no worries at all.
Any information would be greatful thanx.

P.S. its a redtop big port 4AGE.

Do you give it anytime to warm up before ya move off?. Changed the plugs any time?

Common place in carbed motors.

My cresta did it, my hiace does it, and the panelbeaters loan car does it too. I think it's just carb icing or similar? Not sure, i've always ignored it, don't have too many problems with it usually because i leave it idling for 30 seconds while I close the gates before I leave in the morning so it's warm enough before it gets onto the road.

the car in question being injected

Thank you for pointing that out Al.
I Have new platinum plugs in it, leads are ok cap is ok.
I do have a problem with an oil leak, have learned this is a common problem. Oil leaking into the distributor coz the rotor shaft seal has given up due to age. Wondering if the oil getting inside the dizzy is causing a problem. Does anyone know how to fix this problem other than getting a new dizzy or second hand one.

Sowwie - I didn't know that, I'm trying to learn stuff like that

And the original poster didn't mention if it was Carb or EFi.

Maybe the cold start injector isn't working.

by **fatgtr** » Wed Sep 01, 2004 8:55 pm

or its could be just coz of its age it takes a while to get going. mine does it some mornings (those cold wellington mornings) but let it warm up and it bobs your uncle

Once you let the key go from start back to on the cold start injector does nothing so that will not be the problem.
It's a cold start injector not a cold run injector.

My bet would be temp sensor or temp sensor wiring.
Unplug it plug it back on and give it a wriggle.

The engine was rebuilt about 30000km ago, it started doing it about 3000km ago. I'll check the cold start injector.

i'll back matt on that one, sounds like the coolant temp sensor.
Have you tried reading the ecu for fault codes?

by **Monsterbishi** » Sat Sep 04, 2004 10:27 pm

our 4agze acted just like that when we were losing fuel pressure through bad o-rings...

If you state the auto choke is coming out, one would asume it's a carbie, as injected motors dont have chokes :roll:

4AGE's idle at about 2500RPM when cold, revs drop as the engine warms up.

Was there a point to this post? Or is it just forum diarrhea?

Best bet is normally just to leave the car for abit at idle so it warms up sum what and u may be lookin at less of a prob.
Just like the human body really aye wen ur cold u can't be fuked doin shit but wen ur warmed up and got abit more energy in ya its a dif story den.....

Not sure if i'm exactly right but this is my opinion.
As my oldman and my step dad always tell me Don't give ur car any real pressure wen its cold thats wen it starts spitting the dummy.

Hope this was sumwhat of a help to u???

The point here is that the car sohuld be able to run fine while cold, that's how they're designed. Few people can be bothered waiting for the car to warm up before driving it.
