DO NOT ACCEPT THE FOLLOWING FROM YOUR DEALER IF YOU EXPERIENCE THIS............"nothing to worry about, they all do that"....................OR YOUR ENGINE WILL GO BANG AND SPEW OIL ON THE ROAD

 

when you say "cabin shake"?

Mine wobbles a fair bit on tick over.......

 

Crappy idling is a sign the MAF is going. MAF is going, the ECU will underfuel on boost. Running lean leads to knock, knock leads to knackered pistons, and either pre-ignition & a hole in the piston or if more subtle & goes on for long enough, possibly weakens the rods/big-ends & they go, leaving a big hole (or a few) in the engine.
Crappy idling can be a sign.

 

sure I'm being paranoid here......

The idle is fine or at least the rev's are fine - totally steady.

My concern is that you can feel the car wobbling slightly on idle. I always assumed it was the orientation of the pistons and the dealer said they all do it.

 

Yup...... just before the engine blows up

After my new engine it was totally smooth

Well new short block installed............seems to be running smoothly..............fingers crossed.

 

Short block still in one peice (amazingly) Have run in like a good boy (driven it like my nan) not gone over 2500rpm and guess what.....still get sea sick when sitting in traffic. Have once again brought this 'feature' to the attention of my dealer, who once again had told me not to worry and that it is perfectly normal.......why then do I know 6 or 7 people with very abnormal sccobs?

 

What is MAF?? Air-flow meter or something??
When the ECU underfuels on boost where do you get the knocking? In the engine??

 

MAF = Mass Air Flow sensor
Knocking from engine.....HELL YES

 

.....am going to fit replacement MAF......watch this space for an update.......
