1995 Toyota Camry LE 2.2L No Start
Well it looks like it was almost unanimous! I pulled the timing cover and the camshaft seal had been leaking oil for so long, the timing belt became soft and kinda stretched, so it's no wonder that it jumped time. I talked with my customer and we decided to in...
1998 Toyota Tacoma DLX 2.4L MIL Lamp on VIN: 4TANL42N8W
The fix was to replace the egr vacuum modulator valve. The test for the valve is to remove it and see if one can blow through the port on the bottom of the valve that exhaust flows through.
