[JAFF]

hi guys ,girls
on my 320 in the morning unless i give it some throttle when i first turn it over it wont start its almost like its not getting any fuel but it runs fine other than the pick up frm a junction isent very good dosent always pick up that gr8 ne ideas !?

Good basic service is the first thing to try.

[JAFF]

and then wot if that dosent work ?can you buy a new cold start or not really thats the only thing i think could bbe the problem

[Falkster]

Could just need, as Brian say, a good service and maybe the fuel system needs a good clean out!!

Only ancient 320s have a "cold start". What age is your engine?
When you start an E30, you shouldn't touch the throttle. Just turn the key and leave it all to the computer.

its on a H plate 91 if i dont touch the throttle it would just turn over and not start ! this only happens first thing in the morning so i just firgured that it would be the cold start cheers guys i do need to sort this b4 winter sets in 2 hard ,service the car in wot way ?

bung in a bottle of redex or equivalent on half a tank of fuel, also replace ur fuel filter. u could try runninig it on super unleaded and see if that helps ur throttle response, tesco super is 99 octane whereas most other garages's super unleaded is only 97 octane.

alrite ill give that a go ! ,i thought bout a zone chip aswell

[Brianmoooore]

Putting in anything over 95 octane fuel is a total waste of money. No advantage at all!
There's also no point in putting a zone chip in an engine that isn't running properly. Sort the basics before you try the advanced stuff.
Check out the throttle position switch with a meter for correct operation, check the resistance of the engine ECU temperature sensor at various temperatures, check the sparkplugs for condition and colour, check the air meter to throttle body hose, check the valve clearances and cam condition, check the air filter, etc., etc.
