VR missing BADLY after washing engine bay

[FirstVR_JC]

Hope someone can offer some advice here .... I washed and degreased my engine bay today and now the car is missing real bad .. it is spluttering and shaking all over the place with loss of power.

I have to point out the degreaser did get on the injectors, just in case this is an issue ..... degreaser was left to soak for about 10 minutes ..... was washed of with with pressure guerney, but was no stronger than the ones at the car wash.

Have done this before with no issues .... but car is running like a pig now

#my home computer has blown up so have no internet service... at work atm .... so may not be able to respond/thank for advice until i get to a computer ... will be here tonight though#

Thanks..... Josh

hmm sounds like you've gotten urself into a little bit of a pickle. first off i would take the coils and the dfi module off and make sure there is no water and they are all nice and dry, give em a spray with your air compressor, second unplug your leads and do the same, check for any moisture, and also while your at it take the plugs out and give them a check too. also check any other electrical connectors like the ones going to the injectors, crank angle sensor, dfi module connector, iac valve connector, throttle position sensor connector, anything you think may have been sprayed. give all that a go and hope u get it running sweet soon.

Too many things to mention, but, basically it's just a process of elimination with a can of WD40 in hand, check everything electrical, until there is nothing left to check.
It's a slow process, but is really the only way.. :/

b3h3(v)07h...... Thanks for the detail on what to check mate .... I will look into all those and hopefully find the problem, i'm concerned too much degreaser got to the electrical connectors going to the injectors. What is the dfi module connector and where do i locate that? and crank angle sensor? ... i know where the rest are ... cheers!

Cheers... WD40 will get a workout tomorrow!

If you used a solvent based degreaser it will not affect the electricals as much as an alkaline based degreaser - check the label. The cheaper alkaline based ones etch aluminium and basically act like diluted caustic soda or paint remover.
Apart from the above, sometimes it also helps to have a fan blowing over the motor for as many hours as possible...and also in the sunlight to naturally dry the electricals.
Good Luck.

Cheers mate, i will check the lable to see which one it is ... i assume the alkaline degreaser can cause permanent damage.

If left and not washed away it will corrode things quick-time.....but if you flushed the area pretty good it should be OK. The main problem with running the engine when it's missing like mad is that you can damage the coils/DFI module and leads due to the high voltage shorting out - this then causes carbon tracks which also short out. But that's a worst case scenario and you will probably find all is well once it's dried out.

OK ... thanks for the replies fella's, i am often impressed with how helpful people are on this forum

hi mate, i had the same thing after degreasing my motor,

checked each coil with a multimeter set on 20k ohm, do one coil at a time, just hold 1 lead on 1 terminal, and the other on the other terminal and make sure u have resistance of about 6.00

check each coil and see if they all check out

my middle coil2-5, was buggered, car was shaking and wouldnt move out of the driveway properly.... changed it and its sweet now

i know someone that did the same,drove it around for a day or two and ended up needing to replace the coil as water got under it and with the driving it stuffed it

What did the multimeter read on the buggered coil and which terminals do you test - the two that go to the plugs or the ones that plug into the DFI?

An update on the problem ... everything is fine, next day once everything dried out the car ran as normal. Still went over it with the WD40 for good measure. While at it i decided to put my 70mm throttle back on ....

hako,
i tested it on the two that the plugs go onto, and the good coils showed up at around 6.00 on 20k setting, the stuffed one showed nothing, when i turned the dial to the one up i think 200k, it showed 1.26 and it was rising slowly,

the next day when i checked it, it had no resistance on any setting, haha
