97 ZJ Idles up and down Surges and bucs in higear
Like my title says I have replaced Up stream O2 ,TPS,IRC a used one from my 96XJ,Cleaned the TB and installed an O2 spacer on the Down Stream O2 sensor. Every time I install a new part the ZJ runs good for about 2 weeks then it starts to run bad again . I tested the Fuel pump with a tester and got 45PSI. on a Scanner it read that LTFT 0.8 is LOW . What should I try NEXT ?????

Once it warms up to 220 it will run better.
