Rotten eggs and really bad running!
« on: 24 February 2008, 19:05:03 »

Hi
Just gone out and the car has a problem.
1. Very lumpy idle
2. Rough and unsmoothe acceleration.
3. Very strong rotten egg smell.
4. No EML
5. Like a constant misfire

A bit stuck, so hopefully something obvious to someone.

p.s. To anybody that knows me, I apologise to anyone how has pm'd me but I have been having a lot of personal problems. Hopefully be back to normal soon.

The smell is from the cats but I wouldn't no if there causing the missfire could be dodgy lambda sensor or something like that.

Is there a standard check I can do to confirm cats or sensor. I would have thought that lambda sensor would give EML

Nice to hear from you Rob, hope things are picking up for you :y

I wonder if you have a blocked Cat... stick a rubber glove over the exhaust and see how fast it inflates :D

Hi James,
Nice to see ye olde faithful  ;)

I have done that, remebered from last time. Inflates quick. Exhaust seems to be putting out at the correct rate but really stinks. I tried a good foot down also to try to clear any potential blockage but no effect.   :(

First step is to check there is a spark on all the plugs / leads are ok

Also try a compresion test if that proves ok...

Of course you are mate :y

Just unplug the DIS or crank sensor (to stop engine firing)..  screw the compression tester into the spark plug holes one by one... crank the engine and take the reading...

Oh, and get a "gunson" tester, they are great value for money (bout £10 on ebay, or £18 in halfrauds)

It certainly sounds more up front than exhaust :'(

Similar to when I had ICV and rear multiram connections wrong way round but 5 times worse

A compression tester!  ;)
There'll be a specific figure somewhere but you're more concerned that all cylinders are within about 10% of each other.  :y

I would expect readings to be over 200psi

Just pray you don't find nil compression on one cylinder  :-X

What is the worse case senario? Can I drive it very gently in the meantime?

 If you find nil compression on one or more cylinder/s, then it could be head gasket/s gone, cracked head/s or burnt out valve/s.  :-/
 
 I would try to find out what the problem is frist before driving  :(

 You will find the paperclip test here
