Got any reccomendations on brand of battery to go for? My one's almost shagged and my car has been a bit sluggish...

I bet on Marshall/exide,This comes from 20 years of diesel experiance

I would suggest a NS70 (or NS70L I cant remeber which way around the terminals fit)

It is the biggest battery that barely fits in the hole

+1 for the NS70. Awesome battery.

+1- got 1 in each of our two cars, subs and amps dont seem to affect it ha

im still having issues starting mine. sencers fine. cant fit bigger battery then 600cca.

Mine stalled today at the lights. Im guessing cos it was cold. The old possum links dont like cold starts too much. MIght have to dial the idle up..

was very odd. Never done it before or since.

How about something more basic like a tired battery ?

that was my 1st thought!

So +1 it is probably the most common reason I have experienced

[embai]

i fitted new battery in mine and still same, went to have ecu scan and everything was fine, assuming sensor all fine

spark plug problem?

fuel filters?

it is only hard to start during cold....

???

Be the coolant sensor affecting cold starts

Where are you guys taking your cars to? Maybe leave them there overnight so the service guys can experience the fault for themselves with a cold start in the morning? That way they can hook up the Select Monitor and log data on startup too.

coolant temp sensor giving an incorect cold temp reading wont necessarly give you a cel code or store a fault in the ecu memory it will simply just cause the ecu to miss calculate the amount of fuel to inject during cranking. (most prol thinking the engine is warmer then it really is meaning not enough fuel on cranking!!! = hard to start when cold... Use a scan tool on the car when its cold and see what the display says the coolant temp sensor is reading deg C vs what the coolant temp actually is! (close to surrounding air temperature if the car hasnt been started .

[Swindog]

Thats odd a. Mines been hard to start the last two mornings, but its been -4 overnight and stuff. Takes a couple cranks and there must be some moisture frozen in the IAC cos it idles up and down for 10secs then idles ok.

The legacy has been hard to start too.

[Guest]

How many cranks does it take till it fires?? does it run fine after that?

[Swindog]

If i pump the gas a couple times while its starting its ok which makes me think its a tune thing. On a warm day, not a problem at all.

I normaly let the pump charge before i start it everytime, the amount of time for that is dictated by the abs light (my wee pet starting procedure)

But ive had it in the garage the last few nights and in the morning its sweet as to start.

It always runs fine mate. Never ever had a problem with it.
