What does it smell like? Gas? Dirty socks? Oil? Coolant? Burning?

 

[bigytwotone]

like it is rinning rich some times its really bad.

Is the vehicle allowed to fully warm up or just used in short hop type of errands.

 

[bigytwotone]

The truck drives back and forth to work about 1hr each way so 80kms each way. There are no codes on the truck eather

im not a mechanic but on previous cars when i had a problem with it running rich like that was due to a faulty O2 sensor but that was a 00 lexus rx300 just figured id ad that in. atleast sensors for these are a fraction of the cost for the lexus think i paid 250 for one o2 sensor good luck

 

[Lima Tango]

Do you have any way of observing the behavior of the o2 sensors, air fuel ratio, etc? I can see all that with a cheap ELM327 bluetooth OBDII device and the Torque app on my phone. It would help to diagnose with that info. Going in blind, I would start with inspecting for fuel leaks around the tank, lines, and injectors; cleaning the throttle body; and changing the o2 sensors.

Running rich is probably the FPR.

Fuel smell could also be a bad fuel filter.

Fuel smell could also be a bad fuel filter.

A bad fuel filter would just get clogged. A rich smelling engine means to much fuel is being burned. The fuel filter would be ruled out in this case. That is unless the fuel filter was on fire and burning fuel.

My advise....Don't light any matches or cigarettes near the truck until it's fixed....Have you checked for any fuel seepage/leaks?

well the good thing is i don't smoke lol

where would i get one of these bluetooth obdII things??? and i have an Iphone what would i look for to get the app.???

do a google search for the bluetooth unit... also the app is called torque

 

[Hypnotoad]

I don't think Torque is for iPhone. There are similar apps for iphone. I believe Rev is supposed to be a good one.

Nothing on iPhone will work through Bluetooth as Apple would not allow serial connections. If you absolutely need something to work with an iPhone, look for ELM327 that works over wifi. eBay is the usual place for these things. That's where I got mine but shipping from China might take a while. Running it rich like that will kill your catalytic converter.

So happy I never got into Iphones they really are over rated IMO but anyways. When my CPAS started going bad my TB did the samething yours is. It wasnt for quite some time that it tossed a code.

 

[jeffro312]

There's an iPhone app called dash command

 

[CaptainXL]

I would also check the exhaust backpressure. Running rich for too long with a bad tstat will coke the catalytic converter.

These apps aren't very cheap and they don't have the best reviews

 

[TangoBravo]

Yeah sounds bout par for course as far as Iphone goes. Yet one more reason why I love NOT using an Iphone.

My buddy used to have Rev a few years ago and thought it was pretty good. It looks like from the reviews it isn't very good anymore and suffers from not having an update for a couple years. That's a shame.

Running rich is probably the FPR.

I would agree with this. Look at your fuel pressure regular. There is a vacuum hose that goes into your air resonator. I just pulled mine the other day to replace the spark plugs and my resonator was full of gas..... that means gas is going everywhere. My garage smells like gas and I can get a slight hint of it in the cabin too....

Also check the Cam Senor as well
