If it's truly flooding, the computer should be picking up on that. Someone really needs to look at the data stream if it feeds one and analyze the sensor data to look for an issue. It can be injectors, wiring, regulator, temp sensors, MP sensors, fuel pressure. Any number of things.

This injecter when bad would just keep dripping. Remove the duct and check them.

Something like that would set a code and put the light on.

Had someone trying to fix it for 2 weeks, they changed the temp sensor, changed the fireing order back to factory. Before it was not getting alot of gas and now it is.I changed the module on the distributor, and changed the voltage regulator. Spark plugs. Cap&rotor, and the pick up coil before I sent it to the mechanic which has no clue with older cars it seems.

Had similar problem with my Dad's '86 T-Bird, on his it was inability to idle (sometimes it would, sometimes not). It was the injectors, they are not "Monitored" by the Computer, The computer just "operates" them. However when they act up, they do make other things throw codes randomly.

The 1st thing we did was the coding w/ the Scanner--It take s a bit to catch onto--listening/ watching the flashing light/ beeps and counting---watching it go thru a sequence

I was pulling my hair out and made several trips to the salvage yard and obtained nearly every sensor (2-3 of each) off of T-Birds and Cougars

I thought surely they all cannot be bad, I got a bagful for like $10!

My intentions were to figure out which one was being evil----THEN BUY A NEW ONE!

My Dad and I wound up taking it to the feller that the stealerships take their problem cars to. He let me watch the process.

Everything was in perfect order, He put stuff on an oscilloscope, and explained what he was doing. The only thing he came up with that was not perfect was the TPS--I had replaced it with 2 from the salvage yard and wound up buying a new one from Advance Auto (This new one was supposedly bad)

This feller even confirmed "Base Idle" was dead on (another learning experience). Don't mess with the adjustment screws--I learned that throws the computer out of sync with the sensors---there is a specific procedure to get it right----at least I had got it right before this guy checked it out

Dad paid the feller $200 and off to the stealership for the "OEM TPS". It's cost was much more than Advance Auto

Guess What?

This did not work, in fact, I took it back and got another

Same deal. Will not idle!

I was on the Verge of Suicide.

My buddy had went back and got the whole throttle body off of a wreck that had low miles, for $20.

I laughed when he showed up and gave it to me.

He said this is the only thing we haven't tried, the price was right!

Every other knowledgeable person (I talked to many, many people) insisted it was a sensor problem and I had spent a MONTH changing everything in the world.

I even had a composition notebook started w/ what I had done, the various code changes I got, How it ran, how long before it would not idle

It was the Two INJECTORS the Whole time!

Need a Bagful of sensors?

I am not a Paid Mechanic (as you can see) I do know Jeep CJs very well (They don't have a computer)

I hope this could be your problem, maybe you can try some used ones prior to buying new ones, just to be sure.

You could just use the excuse I use to justify getting new parts, whether it's the problem or not---"It's gotten the car to $300,000 miles already, something new is just preventative maintenance. The car is paid for, this is way less than one payment on a new one!"

Not true. The computer monitors every bit of fuel going into the engine through the 0/2 sensors to maintain a constant 14.7:1 air/fuel ratio at all times.

You need to make sure #1 wire is in the right position. The parts store will have a diagram. Make sure its on the distrubter cap correct.

WRENCHTECH IS CORRECT THAT THE FUEL IS MONITORED AS IT PASSES BY THE O2 SENSOR

WHEN IT TELLS THE INJECTORS TO GIVE IT MORE FUEL SO IT WILL IDLE, AND THE INJECTORS ARE INCAPABLE OF DOING SO---IT WILL THROW VARIOUS RANDOM CODES---AND THE ENGINE DIES (EVERY CODE THAT WAS THROWN POINTED TOWARD A SENSOR PROBLEM)

THE INJECTORS IN A '86 THUNDERBIRD ARE "DUMB", IT DOES NOT "SPEAK" TO THE COMPUTER IN NO WAY, SHAPE, NOR FORM, TO TELL MR. COMPUTER IT IS SICK

BEING THAT PAP'S WAS EMITTING TOO LITTLE FUEL AND YOURS IS EMITTING TOO MUCH---I KINDA FIGURED THAT MAYBE YOUR INJECTORS WERE SICK ALSO

I'M SHARING MY EXPERIENCE SO THAT YOU MAY POSSIBLY EXPLORE THE OPTION THAT FINALLY FIXED THE PROBLEM

I TOO LISTENED TO EVERYONE ELSE SAID TO BE "THE MAN". OR."IF HE CANNOT FIX IT NOBODY CAN". OUT OF A DOZEN OR SO COMPETENT MECHANICS WE SPOKE TO, NONE SUGGESTED THE INJECTORS.

EVEN WITH THE HEADACHES AND TIME, I STILL FEEL WE STILL GOT OUT WAY MORE CHEAPER THAN AT THE STEALERSHIP

I TYPE VERY SLOW AND I WOULD NOT WASTE MY TIME TRYING TO MISLEAD YOU, I JUST TRY TO HELP AND OFFER LESSER EXPENSIVE OPTIONS

I WILL CONTINUE TO FOLLOW THIS QUESTION, BUT RESPOND NO MORE. UNLESS YOU RESPOND TELLING ME I WAS RIGHT. THEN I WILL DO MY VICTORY JIG AS MUCH AS I CAN IN TEXT!

PLEASE CONTINUE TO REPORT BACK, UNTIL YOU ARE FIXED

GOOD LUCK AND MAY THE FORCE BE WITH YOU

Let me add one to that.

Giving incorrect advice isn't helping anyone.

HAPPY NEW YEAR.
