Other problems to look at are, pull the vacuum line off the fpr, it could have a torn diaphram and sucking gas throught the hose into the intake.
Also, check for exhaust leaks at the head and cracked manifolds Any leaks here will draft in fresh air, leaning out the mixture and Oxygen sensor will indicate this to the ECU and richen the mixture up. I like to check tps volts instead of the ohms readings. Read the thread I started on TPS voltages a few days ago. Also, the TCCS system Toyota used is very clever. Google the VF signal in the check connector. Its a checkup on the ECU side of things post O2 correction. its a simple 1 to 5 volt staged voltage check and lets you know if the ECU is adding fuel, or taking fuel away when the engine is up to tempurature. Check it out. |
