MK3 Golf starting problem

[Ferdinor]

Ermmm its hard to explain what it does but ill try, basically when it fires up its running on 2 putting foot on the throttle it will slowly go up and 3 will come in then eventally the 4th will start and i wont have a problem or miss a beat until i next try to start it, its like a bogging/missfire 

Yeah i heard i can get a cable of ebay for it, but money is so tight atm im trying to solve the problem either without spending money or at least find the fault then replace it.

When you say clean of oil what do you mean? i mean the tb is really clean had that of to clean inside the big round pipe from the tb to the airbox there is a small amount of oil but i mean it doesnt seem like it could harm anything? what could that be? 

Where is the coolant temperature sensor mate? i know the one that shows how hot the engine is on the dash is faulty as the needle never moves..........its on top of the engine near the 1st or 4th spark plug whatever way round they are counted? but surely that is just a monitor not a controling sensor? is there another elsewhere?

Nope not losing any water or oil never leave a puddle and the level is always around the same mark, i mean i end up under the bloody bonnet every day 

Cheers for your reply mate hope this is enough info for you

With regards to losing coolant, if your head gasket was blown the coolant makes its way into the cylinder and on the initial start up the engine will run very rough until its essentially gets rids of the coolant in the affected cylinder/s. If you are not losing coolant then no need to worry about this but you won't find puddles on the floor, its leaking into the engine. What you said about the coolant temp gauge not moving is a little concerning as you don't know if the car is overheating or not. If it did over heat then it could have blown the head gasket.
Check the coolant level, mark it on the bottle, use the car and on the following morning check to see if its dropped significantly. Or take the spark plugs out after spinning it over a few times after your first start up of the day and see if they are wet with coolant.

Your throttle body seems clean from what you've said so it should be ok, some other VW's cut out and experience all sorts of problems with oil in the TB.

Is this your engine? 1.4 right? Basically under the dizzy theres a round sensor with a yellow ring around it, thats the coolant temp sensor. It sends a signal to the dash for the gauge and one to the ECU for fuelling etc. One side can go down and the other can work like in your case but check the wiring to the sensor as far as you can see it. Costs about £15-20 from somewhere reputable and not too difficult to change
