I cannot get any short or long term fuel trim correction readings. I have All-Data DIY, and it says this vehicle does not support individual oxygen sensor fuel trim adjustments, there is nothing wrong with the vehicle, I just wanted to know if this is correct and you cannot get any fuel trim readings from this vehicle.

They are viewable on live data and freeze frame data on a Snap-On scanner.

If you are reading in the Global OBDII system, you can find the readings there. Being way2old is why I need help from younger minds machinist Anonymous Poster Apr 22, 2009, 4:00 PM Post #4 of 4 (3332 views) Re: fuel trim corrections Sign In Thanks for the advice, I have tried all that you've have suggested with I think no results, except I get the reading -100.6. for all the short term and long term readings, and I do not think it is running lean because I do not have any codes and it just passed smog. But I will try to run some carburetor fluid thru it and see if the mixture will get richer.   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
