Got a Prob woth the damn z6, it seems to be running on 3 cylinders, and did the following to see what it could be. #2 is dead

1.swapped spark plug wires and spark plugs around.
2.changed fuel injectors to different ones.
3.got spark at both dizzy cap and plug end of wires.
4.all injectors click.
5.not burning oil and anti freeze is clean.


so i'm woundering if a bad valve adjustment...too tight, may actually kill a cylinder since I've read how people's cars won't start after one, then turn on when they redo it.

also read how an ecu my do this...then again I am getting fuel and spark.

motor revs ok, just idles funny, I pull wires and idle changes until I hit #2.

Please help with some experience//ideas

 

maybe an o2 sensor, or any CEL's. my car is acting the same around idles (even shutting off on idles). i got a cel 3, 5 (map sensor). maybe that's your issue as well?

 

nah cant be that, I got no check codes...well not until I hit 5k rpms then I get code 21 and 14...vtech and ICVA or what ever you call it..but how the hell that effects a cylinder from firing properly?

thankfully it dont die on me

 

if you had a valve adjustment done and it was done too tight it will give you this situation.. i would pull off the valve cover to see if you find anything goin on under there rotate the crank pulley with a 19mm and watch to see if everything is moving freely and if everything checks out do a compression test and come back on here with the results

 

will do the valve adjment in the morn...hope it fixes the damn thing

 

damn...would've thought my car be dead right not...but so far 3 weeks...1k+ miles.

well, after I did the valves still didn't get any noticable difference. Motor still has all its oil and pretty clean...

so now i ask, has anyone ever have a burnt valve and kill a cylinder. if it were the rings, wouldn't it be burning oil//smoking, which it doesn't.

well, ill just run it like that, does pretty good on gas

how much could i sell the car as is with an extra 99 Y8 motor with 80k miles that just needs the crank swapped out (stripped pulley bolt).??? its an LX with 150k and usual dings from the mall.

Thanks
