Ok this things starting to cost me lots now,
It's a 1.8 16v Astra CDX 2002 (Apparently a 1999 Model)
In the past week to tackle a suspected misfire its had...
- New Plugs
- New Coilpack
- EGR Both Removed & Refitted
- EGR Blanked Off
- Lambda Sensor Replaced
- Throttle Body & Inlet Manifold scrubbed (They literally SHINE now!)
And ive not got so much of a misfire now but according to my dad who seems to be an expert on it... it's still only firing on 3 cyls. Now the only things i can think of are:
- ECU F**kerd
- Wiring Loom hacked, (Seems somebody has had a play before and hacked up some wires, all been checked tho!)
- Something else!?!?!?
My next big job is to remove the wiring loom tommorow and check each & every wire from the ECU to the Engine has full un-interupted continuity(sp?)
I'm getting no Engine Management Lights at all either, And if it makes a difference both my Traction Control & ABS Are perminantly lit in my dashboard.
Anymore help would be REALLY REALLY Apreciated, im giving it until next weekend before i begin considering taking it to the scrappy! lol
