Hi

Check
Air and Fuel Filters and PCV valve
Vacuum hoses for cracks and loose fittings.
EGR valve sticking
Spark Plugs and Wires for wear and even gap
Idle Air Control (IAC) selenoid, remove selenoid and using a rag wet with carb cleaner wipe sensor clean, wrap the rag on a wood or plastic stick and insert it into sensor housing making sure not to scratch walls and not spraying directly into housing or sensor.

Keep me posted

Runs rough and misses badly when cold. once warm it runs fine.


This sounds like a problem with your choke. Check that the choke shafts are free and that the choke is able to close when the engine is cold. A spray with penetrating oil will often be enough to free the choke. Otherwise check that the system that operates the choke is functioning.

1995 lexus sc400 heater works while driving. cool air when stopped. help


Heater cold when at idle: Try stopping on a steep incline--does the heater stay warm? If yes, what you have is an air bubble that hangs at the heater hose until pressure from the water pump blows thru it as the engine speeds up. Park on an incline, open the radiator cap, run the engine until the thermostat is open, and fill the radiator to the neck. Wait until the level stops dropping and make sure bubbles don't continue to come up. If they do, you may have a blown head gasket that will keep forming these bubbles until you change the gasket. Please let me know if you have questions.

remove the 2 10mm bolts on top that you can see, then remove front part of inner fender liner you will find 2 10mm nuts. you will need a long extension. Recomend using duct tape around feneder area to avoid scratching.
