Outer Limits 4x4 Board

first up ... the names dave. had my '93 1fz-fe 80 series for like 2 years now. only recently had this problem...

one day my old man wet down the motor in an attempt to wash the car for me. ... damn he did a good job... thanks dad.

but to his amazment the car took forever to start... wet dizzy n coil WD40.
Finally the car started, when it did it would only revv to 2k, then it was like the injectors would cut out and would not re-engage untill the revs drop to 500-800 (idle)... about 3 hours of wd40'in and no clue.. i closed to bonnet left it over night and woah and behold it started, and no problems...

it was fine untill next time i went 4b'in, and washed it again. and it started on me again. this time i was at the car wash and had to drive home usin no more than 2000 rpm's... not too easy..

please any idea would be helpfulll...


also if it helps my fuel econ has gone to crap in the last couple months.... like gettin 3k per litre if im lucky.


thanks for any help you all may provide. Dave.

not sure if you are running a air flow meter, if you are this could be a problem.
when the car is running is it missing.

an Afm is the grey box between the filter and the intake mani... if yes then yeah i have . and no i dont believe it is missing at idle or running

dave

mate if you wet you air flow meter you will have all sorts of problems.
this will cause most of the problems you have asked about.

so whatrta u reckon. pull it apart dry it all out. silicon it all up real good when i seel it back up??

next time you wash your eng keep it running then you know what you wet when it starts to run up the shit

it may already be to late, it might be stuffed already.
but sometimes you can dry them out and they will work fine.
but that is one part you dont want water getting into.
try drying it out and see how it goes.
if its still no good try and swap in with another one and see if the runs fine then.

cheers guys. most helpfull. will try n not wet that shit from now on. still not happy with overfuellin... i can smell fuel all the time... whoops forgot to mention that. but there are no leaks.

meh.

the airflow meter can cause the engine to over fuel as it tells the computer how much air is going in so it can work out how much fuel to inject in.
If it is stuffed and telling you ECU that there is a heap of air going in, it will dump a heap of fuel in.
just a quess. hope this helps.

You have done two possible things
1 spark plugs 3 and 4 right under the throttle body (where the air goes into the motor) are flodded with water, clean and dry them means taking alot of shit off, but this is real common...a new set of leads if the others are effected by oil is the way to go.
2 inside the dizzy cap water can get and stay and do this aswell, usually after a river crossing with this thou, if he used pressure cleaner then quite possible....go clean em up and you will be AOK

I second this. It would be pretty unlikely that you have got water into your AFM as they are pretty well sealed, but if you take your dizzy cap off, you will notice that on an 80 it has 2-3 breather holes. I have filled mine up and run a breather up to the firewall. As dow50r said, plug 3 + 4 is also an issue. Unfortunately, 80 series' are prone to water ingress and will still cough and splutter after water crossings etc.
