i just checked a couple sensors on my 88' 4.0 renix and the tps was out of adjustment by about 10%, also the manifold air temp sensor and the o2 sensor are bad. once i replace these two sensors and adjust the tps will that make a big difference in my jeeps performance/gas mileage. because right now it is very underpowered and has bad fuel economy so i'm hoping this will help.
