Need some help here,
For the past 2 months I have been trying to troubleshoot what has been going on with my 2002 Supra 22SSV. It gets out of the hole fine and runs like a champ for about 1-2 minutes then it shuts down (not off) and will only run at idle speed. If you let it idle for 20-30 seconds or turn the key off and restart it, then the process starts all over. Below is a list of things that I have changed.
Spark Plugs & Wires
Low Pressure Fuel Pump
I ran a fuel pressure test and it never lost pressure. A couple days ago I took it out and unplugged one of the sensors (not sure which one but I think it was the temp sensor that goes to the computer) and it didn't shut down but according to the temp gauge it was running around 220 degrees. This got me thinking that I had either a bad sensor, thermostat, or impeller was bad. Yesterday we took it out after changing the impeller and it did the same exact thing, so I changed out the thermostat and took it back out and I had to shut it down because the temp gauge was reeding around 240 degrees but it never shut down. It usually always shuts down around 200. I am going to check the thermostat today to see if I may have put it in upside down and I was also told to check the transmission cooler for trash.
Does anyone else have any ideas????
Its hard to get a good run in 2 minutes at a time.
