Asking for help from middle east

[ra3i ss]

hey guys


i have chevy lumina ltz which is commodore vz
the engine alloytec v6 done 190 ks
The problem is when hard accelerate the car hesitate but after 3000 rpm goes fast and smooth (i mean full throtle from zero) and when crusing at 90 km/h i increase accelerator little misfire come but if i push more accelerator and trans kick down every thing become fine .
what i am feeling the car not geting enough fuel under 3000 rpm i dont know the reson
I change fuel filter , spark plugs changed 130 ks , i check for intake leaks every thing fine.
i take the car to dealer the said every thing is fine just need tune up( spark plug ,coils , fuel filter , intake gas kit )
I am not Convinced to change all these part (i think AFR problem)
so what you say?

I've said it before ... I'll say it again...

2 words my friend..

Flux capacitor

[ra3i ss]

What is Flux capacitor ?

[aaronevolution]

Check your exhaust/cats for blockages?

[MY VZ]

i know they are on the exhaust but where are the cats located, if some one could post a pic of what one looks like that would be awesome.

And i assume to check for blockages you just unbolt and clean? What would you use to clean them with?

Wouldnt something come up on the computer at the dealer if it was blocked up?

Flux capacitor is trolling for no aparent reason.

[one_and_only2004]

Coils on these things are notorious for failing aren't they?

[greenacc]

Yeah probably something minor like the dealer says, but he's just geussing and changeing everything to find the one thing thats causing problems. Could just be 1 coil not 6.
Could be the transmission fluid needs flushing too. That can cause ruff feelings lowdown.

[mummbles]

COuld also be plug leads breaking down under load. Cheap thing to replace anyway.

pretty sure these things don't have spark plug leads.

When I had a blocked cat last year, it took 2 weeks before the warning light came on.

Dont pay any attention to this guy, I think he may be on the piss lol. Flux Capacitor is a component in the car in which Marty and Doc used to travel back and forth through time.

If i read that correctly you changed them at 130 and now the car is at 190?
Dude thats 60000ks without a proper service.

A mate of mine had the same problem. Just give it a full service and it should fix the problem.

[Stewlz]

Maybe new battery or alternator upgrade to provide the 1.21 jiggawatts for the flux capacitor

[ra3i ss]

Thank you to all
I am going to check
1- Cats(in our country we only have one O2 sensor every side befor the cats not like yours bank1 and bank2) so if blocked will not appeare code
2- Transmision flush (it could be because the transmision cooler craked in 150 kms and water got in transmision )
3-spark plugs i will change it any way

[njmartin]

A blocked or dirty fuel injector would cause those symptoms. You could try running some fuel system cleaner through a tank of fuel (you might be lucky) but best to have them removed and professionally cleaned.

Am working in offshor company (sea survey) i am far away from my car after 10 day going back and will post some pic

Already try fuel cleaner nothing change at all
thank you bro

The fuel cleaner only works sometimes... most of the time its a waste of money. Even "on car injector cleaning" is hit and miss because it flushes the rubbish from the fuel rail and lines through the injectors and can make the problem worse..
I put up with a sick car for months until I finally pulled the injectors and had them properly cleaned off the car. Made it run like new.

A new air filter could help also if you have dusty conditions over there.
