or dirty injectors help i just bought her and want to enjoy her

v6 3800

 

can aany one help me with my maro

 

HC is unburned fuel.

I think that your catalytic converter is shot.

You say the check engine light was on?

Did you get the codes read?

How many miles on it?

It could also be the O2 sensors have failed or they are not reading properly.

Sent you a PM.

 

catty converter passed emmisions.... um 165000 miles... i just replaced the 02 the codes i got were left bank 02 evap leak cylinder 6 misfire and egr running at 10%... i replaced 02 cleaned egr tightened gas cap an replaced plugs coils and wires.. now its just a misfire cylinder 6 when i get the car read....

this just started-----> when i rev it in park it starts to cut out at 4000 rpm... it takes a second when i first star it...
i was thinking injectors or and fuel filter

 

Your misfire Cyl 6 is probably a bad coil pack,some times you get duds from the parts store.

 

ok i will look int it thanks


but i does pass the spark test

 

For voltage or visual spark?

It could still have visual but not be strong enough to fire the plug.

 

yea just to the eye.... but if it was a coil wouldnt i have multiple misfires???

i seafoamed her too and there seems to be a difference but still hesitates when first strarted... i put bg fuel injector cleaner in her as well... so when that tank is on E im going to put the new fuel filter on then maby see whats up....

 

Coil packs are cheap and usually the culprit,make sure you use the new seal it comes with.

 

ok yeah i didnt use those i will have to put those on... yeah the old ones looked good....
