16v cuts out????

[joey-gti]

hi all, got a small prob with my 2.0 16v, she seems to cut out a lot, mostly just after starting up, wont start without giving her some revs and engine cuts out when for example... driving along, come to red light, foot of the gas to brake, revs drop and she cuts out....

im thinking coil pack... any thoughts?

jamie.

check the vacuum pipes - you have a post TB leak somewhere

my 8v was doing this a while back.

I took the all the pipes off back to the throttle body and gave it good blast with carb cleaner...gave it a right good clean..also got the misses to rev it as i sprayed some down the TB too.

Gave everything a good clean and it seemed to clear up.

....take the panel filter out and give it a going over with a dust vac.....

all the vacuum hoses seem ok, it seems to not cut out after a few mins of driving, but the other night i had the sterio,light,wipers goin and just kept doin it....

 

[joey-gti]

ok, so its not a 2.0, is a 1.8..
took all the spark plugs out and they wer in really tight and the plugs and lead ends wer covered in oil, cleaned everything up and put it all back, checked the dizzy cap and rotor arm and they both need changing.

that's easy then... show your car some love

could be the coolant temp sensor, fooling the ECU into thinking the engine is 'warm' and under fueling it when it's actually cold.......

only about £10 for a new sensor from GSF/ECP

Cheers andy, sounds like a plan, put vagcom on it today and couldnt find any problems, had a new coilpack and dizzy cap last night, deffo think it needs new pugs. she just needs some tlc i think!!!!
am really lovin her tho!!!!

 

[m0rk]

vag-com is very very basic on the old ECU's

barely worth the effort in fact.

Good old fashioned servicing is what will see you right 9/10

 

[joey-gti]

i agree, it didnt really do much,its more for newer cars i guess, and its much more fun to have a beer on a sunny day n get ur spanners out to work on the car!!!!

 

[joey-gti]

a few mates are telling me its the idle control valve?????

where is it on the engine and does any1 know where i can get 1 as ive had no luck....

 

[Fl@pper]

stuck down into the front of the manifold between inlets 2/3

undo the black cover that holds the plug leads down and it's under there at the front plain as day

#1 but follow lines to see it's central fitted

 

[joey-gti]

sayf fl@pper! which bit is it on that diagram?
is it number 1 or 15?

 

[Fl@pper]

number 1 - here's a better pic

 

[joey-gti]

ah, there it is!!! woop woop, cheers buddy

 

[joey-gti]

well i finally got an idle valve, cost me £15, took the cover off to get to the old one to find the plug hanging off............

DOH!

ah well, plugged it in and shes idling sweet as!!!!!
