running seriously rich.

Running extremely rich(tooo much gas) is the chief cause of black exhaust smoke...

1. stuck open injectors will cause this..

2. Improperly installed o'rings in the injector rail will also cause this issue.

3. possibly a malfunctioning o2 sensor could cause this...(bad wiring also)

4. possibly a bad coolant temp sensor(long shot)(or bad wiring to the sensor)

5.

to much gas would cause the hesitation to correct?

internetautomar

#1,2 or 5.
5 being ECU injector circuit fried and causing #1.
3 and 4 don't affect the system that much individually to cause obvious black smoke.

Greeny

iTrader: (43)

Yes,an extremely rich running engine is in effect "being choked" by too much fuel in the cylinders..

mooze

iTrader: (2)

so if its stuck open i must replace?

Greeny

iTrader: (43)

Yes, a bad injector must be replaced...It may be more than one injector though..

Have you or the previous owner replaced any injectors?

mooze

iTrader: (2)

here is link of idle. it just wont correct itself as of now. injectors too?http://s6.photobucket.com/albums/y21...t=SUC50772.flv

mooze

iTrader: (2)

not that i know of. even tho they have correct resistance they still mayb bad

Greeny

iTrader: (43)

Yes it is possible to have an injector ohm out ok,but still malfunction..Not likely,but possible..

And yes,a crappy idle can be caused by bad injectors...


Car work sucks huh?

mooze

iTrader: (2)

any other way to test them

mooze

iTrader: (2)

Question...

Did your car have this same issue before you replaced the knock sensor,or after?

mooze

iTrader: (2)

after. i do remember a slight hesitation before but not like this. there was no smoke before

mooze

iTrader: (2)

when i removed the fuel rails after trying to see what was wrong after k/s replacement i saw that 3 (i think) ports looked wet

Greeny

iTrader: (43)

Did your injectors fall off the work bench also?

mooze

iTrader: (2)

haha no. i put a bag over them and set them in a sink i did take the front rail to a store to get the hose for the fpr

Greeny

iTrader: (43)

I dunno dude,it sounds like maybe you have done something wrong during reinstallation of all related parts of the k/s job..

But it may also be just a fluke that an injector or two may have failed at the same you done your work...

mooze

iTrader: (2)

i bought 6 from ebay. they should be in 2morrow

mooze

iTrader: (2)

goon9

iTrader: (13)

Whoa..... Wtf!?

Well maybe not serious. Just All the wires going to your motor and accessories. I'm a little tempted to quote you in my sig...

Greeny

iTrader: (43)

You might want to remove the d side plastic fender well and check around in there for burnt wires..

Can you post the ebay link for the injectors(just to make sure you bought the correct injectors)

Greeny

iTrader: (43)

if they aren't brand new OE/Bosch in the box you are taking a risk.

iTrader: (2)

internetautomar

iTrader: (30)
