350 tbi flooding

[don]

i dont remember the cam #. i ordered it from jegs and told them what i had and this is the one they recomended. it has a smooth idle when warm. i have full length headers with the o2 sensor in the collector. dont forget i had this problem before the cam change and with the factory exhaust manifolds. i did remove the air pump and i know other people who did and they had no problems.

i do have a new set of shorty headers i am planning on installing

Ok, PART of your problem is the one wire O2 sensor. its cooling off, and sending the ecm back into open loop....I saw that last night on the log, and have been scratching my head untill now.
I would suggest a 3 wire o2 sensor from a 95 truck, but if you intend to install and use the shorty's, we can hold off, but you may want to expedite.
I am going to ponder the low vac issue.

someone already suggested a 3 wire o2 sensor. i had it on for a couple of months and removed it because it still flooded the same.

i made the idle air adjustment and readjusted the tps. i was able to set the tps lower after idle adjustment.

on the 1st log i posted it stopped flooding at 102 degrees. i dont see anything that changed on the readings.

 

[Jims86]

Can you look on the ECM or on the chip, and tell memwhat the 4 letter code is?

 

[don]

akaj is the chip #

Has it ever idled lower than 800 rpm? I am thinking that your IAC is crackin open an awful lot....up in the 100's is not something I am use to seeing.
As far as fuel commands, looking at the BLM and INT, thos are normal for cold start...123BLM is close to perfect.

 

[don]

its always idled the same. it went from 500 to 900 when i pluged the iac in.

i have been looking for a wire harness since its the only thing i havnt changed. finding a used one for an 87 is not easy.

 

[Jims86]

I really dont think thats necessary. If there was anything wrong with the harness, your check engine light would be burning bright. Is there a switch on your diagnostic cable that says "10k"?
