Intermittent problem

[daleyboyVR6 6]

Today all of a sudden the engine dropped power the accelerator seems to do nothing and the revs went between 500-1400 revs like someone was prodding the throttle i turned it off waited for a bit then it started and went fine. Its happened a couple of times the only thing i can think of is that i Jet Washed the underside of the engine could it be a bit of damp or is it a symptom of something more serious,?............ all suggestions will be welcome...................... :-p

Check coilpack/dizzy may have water hiding somewhere. Other than that check all wires are attached and not broken.

Other than that I don't know

Did you spray WD40 over the connectors/electrical plugs after the jet wash to force any water out...?

[daleyboyVR6 6]

No i didnt but will do, firstly it stopped then i panicked thinking it was something terrible, then i put this post up then as i was writing it i realised it started when i jet washed the underneath !!.....what a muppet !..........it hasnt done it since , obviously when your pride and joy stops first thing you do is get stressed then all logical thought goes out the window.............thanks for your comments................. :-p

turns out could be the head gasket, broke down today overheated followed by oil leak, followed by substantial loss of power, really peed off, oh well thats what happens when you have a 13 year old car........................ +o(

could it be one of your sensors isn't working within scope and allowed ur car to overheat...and then u got the subsequent problems..?

[daleyboyVR6 6]

i drove it only for a few miles when it was hot, ive been noticing for a week or two that it was underpowered, although it is a possibility what your saying, i havent had i chance to look at it properly, but if the headgasket has gone then obviously i would replace and perhaps put it on a VAG-COM from a kind soul on this site.............................in addition to the symtoms i thought the exhaust had gone as well as it sounded like it was blowing, so 1) it overheated 2) got an oil leak 3) exhaust blowing...all add up to what maybe be one problem not two or three although any comments on this will be welcome ....................:-p

Its also worth checking the exhaust is ok because if its blocking it could be causing your lack of power and it can cause it to overheat if the gasses are not escapiing properly also the build up in preesure could cause it to start leaking aswell so its worth having an exhaust check to make sure its ok mate.cheers carl.

some good answers lads thanks, will have a look during the week and see whats going on will post up the results cos someone else my develop the same symptoms cheers again...............................also it seemed it was running on 5 cylinders.................... :-p

[daleyboyVR6 6]

After looking at my car after a few days rest, (me not the car) the only symptoms i have now are

1) it seems like its running on 5 cylinders

2)after taking out all the spark plugs they are wet and smell of petrol

Is there any test i can do on the coilpack or is it a vag-com job, any help would be appreciated , thanks in advance.................Dale.................... :-p
