running rich on stock setup??

[americanjebus]

changes to car are as follows.

hg redone to with oem gasket
FIPK
3'' cooleeze dp.
gutted cat.
bosch 110 bov.
metal lower ic pipe

now the issue with my car is that i am running pig rich. like my freind will drive behind me and he will pull up and say "holly crap your exhaust smells like crap dude" i will get on it and i can smell my exhuast with the windows down then i stop and it smells like gas. no real smoke but my freind says he has seen some little puff. i will pull into my garage and put my hand upto the exhaust and then smell it and it smells like unburned gas.

wtf would make my car run this rich having never modified the fuel system

right now on my list is

o2 sensor ( i did a hg swap and could very well have gotten coolant of water on it, and when i did dp swap i touched it allot and just threw it arround the turbo to get it out of the way)

afm ( i dunno i found some oil in acordian hose i may have to clean it)

spark plug (changing it either way)

ic pipes, ( last hope i have pulled all of them off and checked for cracks and all of them are put on tight)

im out of ideas as to why i am so rich, im gettin 15mpg average in town i have been charting my trip odometer and gas receipts.

any other things i can look at before i spend money on o2 sensor (hint hint IJ looking for input)

i have not modified my boost.

How old is the AirCleaner?

Did you also set and/or check your timing?
Mine ran rich when my timing was off.

 

[theDon]

maybe your CSI - mine was bad and I ran rich until I got a new one and it was then fine. You can search on how to test it, I can't recall.

 

[americanjebus]

air cleaner is k&N and its 3k miles old and was cleaned and reoiled like 400 miles ago

doing timing at dusk when daddy heads off to work and isnt arround to ask questions.

im assuming you mean cold start injector, time to pull that sucker off and clean it out, and now that i think of it, i cant remember the last time i heard that little tic tic itc after turning off the car. how much is that via toyota dealer??

 

[shaeff]

that little tick tick tick when you shut the car off is the ISC (idle speed control) valve, not the CSI (cold start injector)

Your coolant temp sensor can go wacko and tell the ecu that your car is way cold and that will cause it to run rich...but probably not as rich as you described.

To be honest it sounds like classic symptoms of a bad o2 sensor and judging by the way you abused your old one that's more then likely the problem. 02 sensors don't like to be molested and by your own admission you're "Chester the 02 molester".

Keep your hands to yourself!

crap well i may need a new isc or something cus that thing isnt ticking anymore. how can i check my isc, i just tryed to take the thing off but i cant get the two screw/ 10mm hex bolts that hold it on and i have zero lighting at that angle, i could feel some little box thingy atached to the backside of the metal portrusion. i cant get any of the bolts loose for some reason i tryed easing them out but didnt give it to much force for fear of breaking or stripping a bolt. does the fuel line attached to it just unbolt like any other or do i have to do something to it , i was giving it some force when i was turning it andi heard this POP. and said oh shit i either busted it loose or just busted it, but the thing wont budge.

getting pissed. so many little crap things under the hood taht dont like to work properly right when i thought i had everything buttoned down and perfect.

Here's a link that should explain everything you need to know about removing and checking your isc.

But yeah if its not ticking after you shut the car down...it's toast.

Don't get discouraged, look at it this way...you could be making a $500.00 monthly payment on some 40 mpg, p.o.s., chick repellant, box with wheels.

 

[shaeff]

it *might* not be toast, if the connection for it isn't secure. (just hoping for you jebus) otherwise, give it a good cleaning, and see if it does anything to help.

the CSI was like $80 from elmhurst toyota new. I've heard of others removing the CSI all together. Not sure if this is going to help you here however, was just an idea. It fixed my richness issue instantly

 

[americanjebus]

ok took off my ISC connecter and reatatched and then took off my cold start temp swtich and reconnected.

i fixed my lack of the tic tic tic and now thats ok.

parts stores are closed so o2 is on its way monday

and well my CSI is going to be taken off tonight, little bugger is freaking hard to get a wrench to. such an uncomfy position. and well toyota dealer is closed but im gonna order a brand spankin new one on monday just cus i dont like dirty parts.

thnx peoples you have cleared up another little detail in my engine bay that i previously didnt understand.

 

[Deeznuts]

i thought the stock 7M-GTE ran rich from the factory

 

[americanjebus]

yea but this was a little too rich,

people driving behind me were complaining of hte smell of crap/clutch burning smell coming from my exhaust.

btw. i fixed it with a new o2 and cleaning of cold start.

Any cat-less car is gonna stink. I ran mine with a test pipe for a whole month before putting on a shiny new 3" cat. I have no desire to smell like an old chevy pickup.

 

[shaeff]

heh, my old DD was '71 chevy pickup. i love that smell!
