Carbon Monoxide emission is beyond allowabale limit

[Khalid_1]

Greetings all,

This is a problem for the technically/mechanically oriented gurus in our trucks.

Two weeks back I took the Syclone to Technical Inspection to renew the registration. The inspection indicated that the Carbon Monoxide level was 6.5% where the maximum allowable limit was 4.5%.

A week later, due to electrical diagnoses of the Sending Unit inside the Fuel Tank, I asked the mechanic to clean the tank content as well. In addition, I cleaned the Air Filter using vaccume cleaner, as I did not drive the truck more than 100 KM since I installed the air filter last year. In addition, I asked the mechanic to clean the TBI and he did that. Added to all that, I put GM Fuel Line Cleaner (the dark blue bottle, with more than $30 value). The tank is still full and I am supposed to use the full tank to let the cleaner make its way through the fuel line.

However, I took it for a test of the Carbon Oxide and to my surprse, I found that now the level of CO had gone up to 10%. It seems like what ever I had done, I just succeeded in increasing the CO value instead of reducing it.

Any thoughts on what I should do or replace? Spark Plugs? Wires ? other items to recue the CO level ?

Thanks in advance,
Khalid

somehow oxigenize the fuel maybe

if you weren't in the desert id use gas line antifreeze or some other additive.
if you have an adjustable chip like turbo tweak you can lean out the idle fuel to help it go away- however im not sure you guys have emissions controls and you would need a o2 sensor to use that chip.

im not a chemist- im an experimentalist.

You are right, the Sy that we have here have the O2 sensor disconnected (the wires are cut from the factory). I will check tomorrow using a sniffer in one of the garages that offer that service and see how it goes.

Thanks for your comments.

try rubbing alcohol to help the fuel- one bottle in tank we have walmarts for this
new development
other board members say that as long as you hook up the narrow band readout from a plx wide band system to the cpu then you can adjust the turbotweak chip to lean out the fuel.
i haven't tried yet because i didn't know that you could run this chip without an o2.
if it proves true- turbo tweak chip sales will double.

Instead of making a new thread, I'll piggy back on this one. How bad will not having EGR work with the sniffer test? I need to do smog by December and need to know if I need to cough up extra money or not.

I passed without EGR, without a cat, and with a 160* thermostat. Granted, I'm running a TurboTweak chip and shut my electric fans off (to build up heat), so that might help. Luckily they didn;t do a visual either.

I should be fine then. 180 degree thermostat and a brand new 3" cat.
