Hi!

I replaced all injectors on my -99 Bravo 1.6 yesterday. 2 of them were dead an one was halfdead..
However, after fitting the new ones i started up the car and the eninge immediately revs to 4000 - 4500 rpm on idle. Then it keeps reving slowly until I turn the ignition off.
I tried to reset the ECU after this but it did no difference, I only disconnected the battery for 5 mins, maybe it was to short time?
The injectors are a mix of IWP064 and IWP001 but they had 3 different colors beige, grey and blue I think. I had to use a mix because this was all I could find.
What's most likely to be wrong? Help me please... :bang:

Now I have tried to disconnect the battery for one hour, but still no difference.

Could it be something to do with mix and matching injectors? Has your injector/engine management light come on?

Thanks for your reply!
I thought it was strange that they had 3 different colors but after reading several threads here it seemed like it wouldn't matter if it had 2 or 4 holes. Is my symptom really likely if the mix of injectors is the cause?

Before i replaced the injectors the injector light came on. Now I've only run the engine for approximately 5 - 10 seconds since it just keeps reving. During that time, the engine runs really smooth and the injector light does not come on.

No more clues what could be causing the engine to act like this?

wrong injectors causing overfueling?

did you remove them from a 1.6 yourself?

This was something I suspected too at first. I removed 2 of them by myself. They were IWP064 and the fuel rail looked exactly like mine.

The other 2 came from another car which I didn't remove by myself. I got 4 from that car but 1 of them were defective. The fuel rail from that car looks different, it has 2 fuel lines whereas my only has 1. But I still got the defective injector from that car and it's an IWP001 which should mean the rest of them are the same.

But the fact that they had 3 different colors makes me suspicious. The 2 blue ones came from the different fuel rail. Does the 1.8 have blue injectors?

does seem a bit odd.

i'm afraid i have no idea what colour the 1.8 injectors are.

i think it may be best to get a full set of injectors from a 1.6 and go from there, could end up chasing your tail and find its actually the ICV is stuck but if the problem wasnt there before we have to assume its the injectors.

Thanks for all help! The problem is now solved.
2 of the injectors had wrong part nr. The blue ones which actually were green had part nr IWP009.
They also weren't fitted all the way in the manifold.

After fixing these issues the car is working again.

Thanks again!

glad to hear its fixed!
