1. Start the engine cold and the engine temperature, intake air temperature and transmission temperature should be within only a few degrees temperature of each other.. 2. Test drive until operating temperature is obtained. 3. Allow the vehicle to cool and repeat steps #1 and #2 a second time.
1. Check for a 1st or 2nd design motor mount. 2. A updated motor mount is available. Technical Service Bulletin (TSB) #01-T-30A is related and gives mount identification information and mount testing procedures

1. Check if the distributor is turning. If not, the timing belt is broken. 2. If the distributor is turning, the timing belt may have jumped.

If the fuel trims are high at idle, spray supplemental fuel around the engine area while monitoring the Oxygen (O2) Sensors and fuel trim to isolate a vacuum leak. Pinch off vacuum hoses one at a time while monitoring the Oxygen (O2) Sensors and fuel trim to isolate a leaking component.
Check the engine compression, specification is 199 PSI. If the compression is low check for the timing belt to be off a tooth or for possible sticking piston rings.
Check the fuel pressure at the inlet side of the fuel filter. Fuel pressure should be 40 PSI or more. Tech Tips:
. Check the blower motor speed control wires at the HVAC control panel on the C2 connector. The Blue wires with colored tracers are the control wires, grounding them one at a time will provide a different speed for each wire. The Black wire is the ground for the blower motor circuit. If jumping the Blue wires to the Black wire one at a time varies the blower motor speed, the HVAC control panel is bad.
