Hi,
did you solve this problem?
I have similar problem... at beggining engine was running on 3cyl. I cleaned inlet manifold and rebuild pressure pump. But with no difference... after few minutes I pressed accelerator and engine was choking and shaking. So I truned off engine and now I can't...
Today I changed fuel filter and spark plugs (old spark plugs were black).
Still the same. First start (cold engine) - engine ran at 2cyl, after while at 3cyl.... second start was OK, but engine is making lot of vibrations. I think it should run smoother. Is is like diesel engine.
Quick push...
Hello,
I bought Vectra C with engine issue (Z22YH). On idle it runned on two or three cylinders (sometimes cyl2 misfire, sometimes cyl4 misfire). It had no power when accelerator was pushed quick.
Desired pressure at idle should be 5000kPa and i had only 3000kPa
Ignition coil spark test is OK...
