hi my car is missfireing also pops thru maf and has blue smoke iv tryed plugs leads and coil but no change also i think its piston 1 as when u remove plug lead on that cylinder it makes no change. when i remove any other lead the revs drop could this be injector also im thinking maybe a valve or piston i have rebuilt other cars like 200sx etc so im thinking of takeing engine out and stripping but im my eyes if im going to do this i might as well uprate it i dont really want to remove engine if i dont have to so trying every think really as iv now got a 2 day old baby and could do with a car

 

Have you taken the spark plug out to see whats going on inside? Although TBH it sounds like something has let go, thus letting the compression back through the maf and the oil into the cylinder giving you blue smoke. I'm sure someone will be along to advise soon. Good look with it, hope you get it sorted.

 

Pops through the MAF?????

 

yes mate it some times makes like a poping noise thru maf bit like backfire

 

Sounds like a head gasket has failed.

 

could be. Or that the injector has failed or plug has failed on that cylinder. If plug it would missfire and throw unburnt fuel out the back and also possible pop back through the intake system. Could also be the valve timing has jumped a tooth. I would take the plugs out and do a compression test, check the injector is getting the correct pulse signal using a noid light or similar.

Have you tried a plug on the end of the lead to see if its firing? could of course be as simple as a broken lead

 

Was this not posted last week

yes mate was posted last week. this is starting to stress me out now also i did think my self maybe cam belt slipt a tooth

 

right iv decided im going to take cambelt cover off and make sure timming has not slipped does any one have a picture were the timing marks are etc also has any one else had there timing slip?

 

So it pops through the air flow meter? That's a strange one.

 

Why don't u take it to a mechanic and get it diagnosed properly? Sounds like u got a bigger problem if blue smoke is coming out the back.

 

i would do mate but im very skint at the moment were got new baby and were i bought new coil pack and leads etc also the garages round my way are useless

 

yes mate but only sometimes when tickover goes low

 

also forgot to mention no cel light on but but before it went wrong it use to come on but only somtimes and only for a few seconds

 

Blue smoke = oil, oil = not good, not good = garage, garage = not cheap.
Not going to garage = even more expensive when the rest of the engine lets go

So your options are as stated above, if its not sorted quickly, and that means a garage job by the sounds, then its going to cost you even more.

hi i havnt used it since it started also i have always fixed all my own cars my self so would rather rebuild it my self than a garage in my eyes if i do it my self i know its been done propley as never had good experience with garages the cars always end up back in there in no time

 

right i have now started stripping my engine when i come across this it has got mastic init and 2 wires was pushed init is this the temp sensor also could this be my problem also the alloy pipe the sensor goes into was loose were circled

 

Sorry if this sounds harsh, but do you actually know what u are doing? If u cant diagnose the fault then I dont think u should be worrying about tryin to fix it yourself

 

shudda taken it to a garage i no plenty of good ones near u as im in maidstone not far from u i believe

 

LOL iv already stripped it bare now engines coming out this week 4 a rebuild do i know what im doing hahaha

 

Fair enough
