Question about 1992 Mazda 929
Just had my car at a garage for it's roadworthy cert, where they found a malfunction with the front demister but weren't able to fix it stating it was probably a fault in the climate control modual. Any ideas on how to go about rectifying this problem without it costing the salt of the earth?
I agree with "emissionwiz". What probably happened was you hydrostatic-ally locked your engine. What happens is when you went through that puddle water got sucked into the intake and into the engine. Water being a liquid cannot be compressed and stalled the engine and most likely bent some internal components. If you can hear the starter click but the engine won't turn over you've got a 99% chance its a ruined engine. If you don't want to believe that try turning the engine over by hand (socket on crankshaft), you should be able to turn it, if not it's done for. Good luck and sorry about the misfortune but next time go very slow through puddles.

Check to see if you are getting fuel to the engine.If not replace the pump relay.Then change the pump if still not working.Check for spark at the wires if you have no spark then change the crank sansor.If still no spark then change the coil pack.

SOURCE: engine malfunction
vacuum leaks on intake manifold,
the air tube between the air filter.
intake manifold vacuum hose.
clean throttle plate with Berryman carburator cleaner
SEE sample picture HERE
Also remove carbon built up behind the EGR valve and the EGR passage tube.
Vacuum leak WILL offset the intended 14.7 to 1 air fuel ratio.
More un-metered air (leaks) will lean out the fuel mixture.
Use small amount of Berryman carb clearer at potential air leak area will help you identify trouble spot.
At idle,just spray and listen for the RPM surge.
The in-rush of carb clearer will increase the RPM on the motor.
Record the problem spot(s) and address it later.
EGR carbon built up require 2+ hours to clean from start to finish.
You will need a new EGR base gasket before your start.
Locate and remove the EGR valve after the vehicle is cool down.
Carefully record the connector and vacuum line (for older vehicle) location by drawing an easily to follow diagram.
Remove the EGR valve.
Inspect the location of the carbon built-up inside the valve and the EGR passage tube.
SOAK these areas with WD-40 spary.
You will need a small screwdriver,cloth hanger and lot of newspaper and time to get this cleaning done right.
RE-SOAK the carbon and let it sit for over-night will also help.
One the last round,pass a shop vacuum of the EGR valve and the passage pipe.
Install the new EGR gasket and connectors.
Allow the vehicle to warm up outdoor to burn up any remaining WD-40.
Take it for a test drive.
