so here are the symptoms of my problem this week.

1. temp gauge is going up pretty rapidly and hovering close to the red.

2. when i turn on the heater it drops quite quickly into the safe zone

3. the fan is spinning

4. there is a slight leak at the water pump until it gets hot and the water evaporates off.

5. check engine light with 1-2-1 AMM no signal light came on for the first time (hole in air box has been blocked off)


AMM passed all tests except one and this was a sticking point between my wife and I

in the AMM tests listed in the bentley they have one for testing the air mass wire in it they say to remove the connector and test resistance at 2 and 3. surely they mean test on the terminals in the meter and not on the connector. The terminals in the meter were in the correct range for ohms the terminals on the connector were out of range. Another air mass meter test has us checking resistance between terminals 6 and 7 on the ecu looking for around 4 ohms and i got 13 ohms. so i don't know.

cleared the codes and the light has not come back on, no holes in lines including flame trap hose and trap is clean, filter is clean, connections are good.

these are probably unrelated issues. but theres always a chance they connect somewhere

any advice would be great
