I jumpered the wires and received code 71 for the EGR system. After a quick web search I found that the EGR Modulator Filter gets very dirty and so I checked that and it was REALLY dirty. I cleaned the filter and modulator and cleared the check engine light. So far so good with it staying off.
There is still slow acceleration. Based on the list you gave and from other 4runner forums I decided to check the throttle position sensor. Here is what I got:
Closed - VTA-E2 -.63k ohms
0.020in gap - IDL-E2 - Open
0.031in gao - IDL-E2 - Open
Fully open - VTA-E2 - 6.25k ohms
VC-E2 - 5.74k ohms.
The 0.020 gap is not supposed to be open according to the manual. I tried to adjust the sensor to get a value for the 0.020 gap and when I do finally get some thing the closed value is under spec at.35k ohms. Do I need to replace the TP sensor?
