hi there. i've noticed a strange thing. i cant get over 4500 rpm. it's like rev limiter would be set at 4500, and at 4500 car shakes strangely too. i've tested it only in neutral. if it matters I'll test in gears. thx.

Hi,

it seems like the cam sensor.. please update your profile with the car

model.. and have a look at the paper clip test..

[dawchiks]

oh forgot about the model, its Opel omega 2000 2.0

[cem_devecioglu]

cam sensor..

[dawchiks]

thx guys.

Oh and one question.

Will it be expensive to fix / change it?

btw the engine indicator on dashboard is ON almost all the time.
sometimes it is not. It has been like that for more than half year.


and not to make a new post:

sometimes when cruising normally,when I put it in neutral RPM drops to ~450, and there has been a few times when it drops under 400 and it just turns off ( dont know that word in english). When this RPM dropping problem But then i reved up a few times to the redline, and the problem was gone. but now i couldn't rev it up.

[cem_devecioglu]

sorry but no idea about Latvia prices..but not something expensive

even here..

your other symptoms are normal due to the problem I think..

[dawchiks]

those symptoms were long before the cam sensor problem. it started just recently.  

how expensive is it in your country?

[cem_devecioglu]

approx .60 $

cam sensor dont fail quicky..will do some play before it become

completely donald..first solve this problem..

yea. thx

Sounds like cam sensor as cem said, but paperclip it first to prove (see paperclip post in maintenence guides).

Stalling, worth cleaning out ICV.

[dawchiks]

yea its probably ICV for stalling, and cam sensor for the RPM problem.
is it worth doing the paperclip test, or can I just drive to mechanic. Not really my car, and the owned doesnt want me to do anything myself. i told its nothing special, and it's easy, but still no

I'd still paperclip it to confirm it is a cam sensor failure

Oh god, the dreaded X20 XEV engines!

Right, do a paper clip test first of all, no doubts it will flag up cam sensor.

Also a dodgy knock sensor cam flag up the code for the cam sensor!  But it should flag up the code for the knock sensor too.

Initially it told me something wrong with cam sensor, changed it, still something wrong with cam sensor! Changed it again...Now its telling me cam sensor and knock, so i only changed knock the final time and hey ho problem solved.

Call up autovaux and ask them for the "improved" version, basically the cam sensor has some proper shielding and thicker wires to avoid failing every few months.

Also as for the 4500rpm limited, its called "limp" mode, basically a safe guard for the engine. When i got my calibra, i was a n00b and drove around in limp mode for months, was no fun

Software update on the engine ECU (dependent on year) also goes a long wat to sorting regular cam sensor errors

[Shagma]

Any particuly year model on the x20xev to be worse than others?
I have '97..
