MX-3.com

cars been playing up recently , it wouldnt start at all one day just turned over but i eventually got it going by turning the key and pumping the accelerator and now it just doesnt idle right it idles pretty low about 500-800 id say then it wil dip and shoot up and down and settle again at 500-800, also when driving along quite often it just dies for less than a second just a little blip this is weird, could have started since i fitted the cone filter??maybe

Did you remove the MAF sensor when you installed your cone filter? That needs to stay in, or else your ecu will think that the throttle body isn't getting any air.

yeah its there and the other little sensor that was on the side of the air box, its the 1.5 btw

any ideas? ive cleaned the tb and checked the fuel filter

Check for cracks in the rubber pipe after the filter - one way to check is to spray wd-40 or carb cleaner or something around the tube when the engine is idling - if the idle changes when you spray - you have a vaccum leak....

Sorry if I am completely wrong or just not seeing it, but it looks like the connector that plugs into your MAF is not plugged in. Just a thought; that would cause it. Like I said, my apologies if I just saw wrong. Peace!

Good eyes! And you right it doesnt look pluged in!

what year is this MX3? his MAF looks a lot diff. then mine lol

couldnt find any leaks, think i need a better camera lol it is plugged in, dont know the year exactly but its estimated year of manufacture is 1992-1993 not sure because its an import, and is also jap only 1.5 16v engine

wel i took it to the garage to get some codes off the diagnostic terminal, got maf, coolant temp, tps and air temp only 1 i havent messed with is coolant temp could this be the problem? also exhaust is leaking / blowing quite bad in the centre now??

im pretty sure now its the coolant temp sensor, i tried to get one from my local parts place but cant get 1 for my 1.5 anywhere i can buy 1 need asap in the uk.. also i was wandering which 1 is it think there is 1 for the ecu what i need and 1 for the gauge is that right?
