while warm it reads 200f so it looks k. The gauge in the dash alsoshows a normal temperature. I never had a problem with the cts.nametakennow wrote:How's your water temp gauge acting?
If it's reading cold, the ECU thinks you need more fuel than you do.
First of all your cat converter is shot if your bottom o2 sensors are reading the same as the top 02 sensors, or your ses light is on TELLING you your bottom o2 sensors are shot. What are you getting for a % of load? If it is high then i would suggest you test your vacuum at idle and clean your MAF (almost all drive ability problems with the series 1 & 2 qg motors are caused by a dirty maf, ask me how I know).mmm_2000 wrote:The MAF works fine, the air flow changes with the acceleration.I also noticed all 4 o2 sensors show between 0.8 and 0.9v at idle all the time. Under load, the same o2 sensors show changes in voltage like they are supposed to from 0v to 0.8.
Here is some data recorded over a period of a few mins at idle:-all 4 o2 sensors show voltages between 0.85 to 0.94v-MAF reading is 0.63 lb/min-engine temp at about 200f and the air charge temp at about 70f
I have a total of 4 o2 sensors.
Any ideas ?
