I've been experiencing lack of power from my omega 3.0 auto elite (2000 facelift model B) It turned out it wasnt firing on all cylinders due to a snapped HT lead, however having bought new HT leads from Opel here in Germany, the engine is still shaking violently at lower speeds/revs. It doesn't sound healthy, not to the untrained ear, but certainly to mine and the 0-60 time is 12 seconds, whereas before it was 7.5. The engine rev's like nuts also but no power at all even after fresh spark plugs and leads. Could this be an Air intake issue or could it be the throttle housing is blocked? I'm now thinking it's an air intake issue or fuel filter?
It's happened only recently and very quickly. the car though has always seemed to "rock" on braking, wheels are balanced, brakes are fine, but this is the same effect i am experiencing now when the car runs at idle. It rocks heavily as though it struggling and requiring some sort of attention I just can't figure out.

Please help! Thanks chaps!

Hiya you need to do the paper clip test and post the codes, then other members can point you to the correct solutions

I have plugged in a diagnostics computer into the vehicle, and no error codes appear, however this diagnostics machine is a friends who is helping me get this problem sorted.. My only question is, does this diagnostoc device have to be of a certain type? If so caould you please specify exactly the make of the diagnostic device and other specs?

Cheers

Read this and use a paperclip

LOL that's funny, it is actually a paper clip test! LOL ahh... thought it was code for the ecu computer jobbie!

HAHA!

Thanks lads will give it a bash, you legends!

Latas chaps

Misfires without codes are often HT related on that engine.

Seeing as you have done the plugs and leads, that leaves DIS.

But see what paperclip comes back with first

Ok today I have started my car again after a couple of days not using it, I havent dont the paperclip test yet as i dont have a paperclip but will do it tommorow. The car is still shuddering and when i put the hammer down to the floor, it's taking about 5 seconds to get to 30.. with my foot right down to the floor.  it's getting really bad despite sparks and leads being changed, its like it being starved of something.

Read the codes

If you want to waste time and money changing things, in headless chicken mode, we can suggest all manner of things to try

I have a suspicion of what it might be but doing the paper clip trick is so cheap and easy it absurd not to check for codes before doing anything else.............

As said ... paperclip it FIRST, then SECOND .. put your location in your profile ... you might have someone who "knows" living close who can assist

A piece of wire. Anything.

We cannot suggest anything else until we know what the engine ECU thinks is wrong.

Did you put all HT leads correctly? Few years ago i accidently put two HT leads wrong on my brothers V6 and have same issues, engine was still running but no power and no error codes.

He's in Germany, from his first post

Ok chaps,

I have obtained a paperclip, and I am shortly about to pick the brains of the beast to see what it puts out in terms of/if any error codes. I believe the HT leads are on correctly, however if this being the case i will double check via my haynes manual to see if i can find exactly what order the ht leads are supposed to go and double check, it's a proper a$$ cracker trying to get to the coil pack though. even stretch armstrong complained when I called him up to ask if he could help me out.   
Righto thanks for the tips the mission has begun will let you know in a couple of hours of my findings!

Thanks again!

Ok ecu codes reveal that I am getting low voltage at the MAF sensor, EGR and Oxygen sensors.. Is there I way I can reset the onboard ecu to default and in turn clear the codes? One of my bosses at work the other week was disconnecting my MAF and EGR while the engine was running trying to help figure out the problem with me when it all first started so I'm guessing he may probably have made those error codes by doing this?

Thanks.
