There is no MAF on your 22re.
You have a Air Flow Meter. And it is BEST to leave it alone...
The TPS advances the timing when you hit the throttle, just above idle.
Check your timing- at IDLE, timing at 7* and at 2000rpm about 14*.
For your smog test;
Pulling the spark plugs and making sure the whole ignition system is working good.
The EFI is pretty much computer controlled all the components need to be working for the system to preform like it should.
Sounds like you have a RICH unburnt fuel condition...something is not right.
Low fuel pressure will spit gas into the cylinders instead of mist and cause a rich condition.
A bad water temp sensor will also cause a slight rich condition...
...anyway I'll end my ranting.
Good luck and keep us posted
Low fuel pressure will spit gas into the cylinders instead of mist and cause a rich condition.
There has been more than one reference to low fuel pressure as being a possible contributor.
I have tested the fuel pump by shorting the terminals F(p) and +B as depicted on page FI-43 of my FSM and detected the 'gurgling' sound of the fuel flowing thru the piping.
If low fuel pressure was a contributor wouldn't other symtoms surface elsewhere also?
The manual shows using some Special Service Tool (SST) for testing the fuel pressure at the fuel injector. Since I don't have a tool I have yet to go down this path.
But I do seem to recall reading on this site, someone attaching a gauge somewhere else. Someone out there with a better memory than mine?
A bad water temp sensor will also cause a slight rich condition...
I have replaced the Water Thermo Sensor. The Cold Start Injector Time Switch tested (ohm meter) within range.
I assume you are referring to one of these two sensors located below the throttle body.
