Help......Car Problem

[crezz]

hi all,

on the way to work this morning (very damp and wet) my 2.0 16v gti was not very happy. It was like it was misfiring, very stuttery/juddery like i was learning to drive. sounded really awefull.

ive done a search and the term 'throttle body' has come up alot.... i have no idea what that is? could this be the problem? where abouts is it situated too?

any info will be so much appriechated

prob be the ignition coil m8 , mine is the same in the wet , and my coil has a hairline crack in the housing . ive seen a replacement on ebay for 25 notes , but im tight at this time of year lol

 

[crezz]

fecking weather! i want to go and spray it with wd40 on its absoloutly lashing it down. it hasent even got light here yet!

my old cordy did this every winter, things i worked through were :-

coil, leads, distrib cap.

dose all with wd40, leads if old may need replacing as mine used to arch when wet.

 

[crezz]

so is that what its more likely to be rather then throttle body?

 

[FR-RUSH]

well id eliminate the easy things b4 tackling the throttle body?

if wd40 sorts out the issue due to damp then you know where your problem lays?

at night i could see the sparks arching from the coil to the engine bay, each splutter combined with an arch.

ps dont touch it when this is happening, bloody hurts lol

im gona go spray the lot with wd40 in a min as its a bit dryer

i was unable to go out and spray with wd40 yestaerday as i was working and it didnt stop raining. if it was dizzy and caps would it of dried out its self? as this morning it was still the same?

Sounds like a similar problem to me, i've got a half day off work today and my car in a garage. Still didnt want to play the other day so i'm going to get my hands dirty an change the oil, oil filter, fuel filter and fuel pump relay (seeing as they've been on my list of things to do for a while now) spray it all with WD40 and then keep my fingers crossed!

 

[crezz]

good luck with yours mate.... is it ok to drive the car whilst its like this all will it damage even more?

 

[FR-RUSH]

Well if you didnt spray it, each night it will get damp in this weather. as soon as the wet gets into the leads then it will continue to happen until you replace them.

the wd40 will help you determine if that is the issue. its only a temporary fix.

 

[crezz]

ok going go do it in a minute if it stays dry, are the gti's prone for this in winter? would replacing it all solve the problem?
cheers

any old car is prone to it really, coil, leads, distrib all have a limited life span and as they get old the rubber and plastic perish and thats when you get damp issues.

i used to keep a huge can of wd40 in my old car as every other morning id have to give the engine a spray in winter to get it started.

not sure about your engine type, but i used to pop off all the leads at each end and give them a squirt of wd40 to ensure all the contacts were free of water. and also give the coil a sray too. dont miss out the lead between the coil and the distrib. if the engine then runs smoothly then its probably time you got a new set of leads.

if after all that it doesnt work then you will need to look into other issues like the distrib and coil themselves, failing that, maybe the throttle body as mentioned above.

but if this has only just started since the wet weather then damp wld be the likely suspect.

hmmmm mine had all new dizzy/rotar arm/leads/plugs at the end of the summer :/

 

[FR-RUSH]

must be a mk 2 thing i went through all of the with my cordy, just ended up being endless tinkering until she past away

 

[crezz]

ok thanks,

 

[Kai_1600]

any joy with yours crez?

i managed to spray it all with wd40 last night when it actually stopped raining! (all of 2 minutes) and it seem to cure it after driving for about 5 minutes once it had warmed up so i think it was defintly a dampness issue.
lucky enough my dad has managed to persuade his boss to borrow the motorbike garage on saturday. we will do it all properly and get out any water and then spray up again before the water gets in. got some over bits and piece to be done too.

Don't just spray the outside of the connectors, pull the plug leads out & do them, whip the dizzy cap off & clean & spray in there too.

locate the engine speed sensor, spray that connection as well & you're 95% covered now
