Help please

Hi,
So I have recently purchased a 182 ? its seems a little flat in the rev range until 5k that goes like the clappers... but there is a bit off hesitation before 5k.... it had the fault code for destructive misfire... done the usual plugs ngk ones, leads,coil pack, and injector.... cleared the code happy days... it then came on for lambda sensor it says bank 1 sensor 2 which I would have thought is pre cat... changed that cleared happy days.... the light has come back on with misfire and lambda again and it's still flat in the rev range..... any ideas????

Bank 1 sensor 2 is post cat mate

 

[Renaboy1989]

Haha just my luck.... would that cause the flat spot though?

 

[Krarl]

Could be as it effects the way fuel is delivered etc etc

injector.

 

[Renaboy1989]

I've already replaced the faulty injector... I have order 3 more to be on safe side.... I thought it was front lambda that control fuelling?
Wih the injector do u think the other mah have gone weak

 

[bloke]

you know renault number cylinders backwards?

 

[Renaboy1989]

Yeah 4 being timing side Haha..... I owned one for best part off 4 years and know the cars inside out but this is just confusing me.... just wondering if anyone had similar problem with a possible solution

Mines was similar an turned out to be timing and injectors.
done the injectors first. Then noticed timing was out when I done dephaser.

 

[Renaboy1989]

That's one thing I never gone involved with timing or dephaser.... is there an easy way to check the timing?

 

[william84]

There is a guide somewhere on here.
Tool for it are reasonably cheap aswell.

map reading at idle will give you a pointer if you don't want to mess around with cam caps etc.

I bought 3 spare sets when I done mines as they are common for timing slip ?

Only if it's done by a windowlicker?

thank goodness am not a window licker then ?

 

[Renaboy1989]

Surely it would be running lumpy or not hitting the powerband right if the timing was out?

powerband?? it's not a two stroke!!

 

[Renaboy1989]

All it does is advanced the timing and dump more fuel its vvt in therapy..... and thanks for answer my question.... not!!!

 

[william84]

Yeah ours felt really flat under 4500rpm then big difference in power once over.
was getting eml to. Low circuit at cat can't remember code.
I just thought I would suggest as it sounded similar to ours.
Injectors and timing as the injectors never really fixed it. Lucky it needed dephaser at time.

 

[Renaboy1989]

Doesn't sound good to me Haha.... try injectors first see what that does

 

[bloke]

thought i did answer your question by saying it's not a two stroke and doesn't have a power band??
