1.Most cars just unplug the electrical connector and remove the two screws and clean with spray carb cleaner and maybe a small tooth brush.
2.(Not to ruin the answer that you posted but using carb cleaner will only remove the gummy buildup contained on a dirty iac valve, the carb cleaner will leave a sticky film inside of the iac valve most likely to make it worse than before. the best thing for the iac valve is electrical parts cleaner being an electrical part it will do the same if not better cleaning the iac valve, it leaves no residue and will lubricate the spring located inside of the iac valve. after spraying with electric parts cleaner let dry and don't get anxious putting it on to early then re-apply it to the vehicle and you most likely saved yourself 50-550 dollars which is the highest I've seen could be more!) oh yeah and to remove it you have to remove the coolant inlet hose, the coolant passage hose, the air inlet hose, the electrical connector and the four bolts holding it on don't forget to remove the negative terminal from the battery just like when working with any electrical component! HOPE THAT HELPS!
There is no EGR valve on an Aspire.
To remove the EGR valve on a 1997 Ford Aspire, first disconnect the negative battery cable to ensure safety. Then, locate the EGR valve, which is typically mounted on the intake manifold. Remove any electrical connectors and vacuum hoses attached to the valve, followed by the bolts securing it in place. Carefully detach the valve, making sure to clean the mounting surface before installing a new one if necessary.
The "lifter" is part of the valve rocker arm / cam follower. It is in the tip over the end of the valve stem. If your Aspire ticks briefly during start-up, the lifter/ lash adjuster is remaining collapsed until the oil pressure builds up.
Remove the heater control valve and replace it.
Remove the throttle body. Remove the 4 IAC mounting screws. Remove the IAC.
It is bolted to the underside of the throttle body. It has 1 harness connector and is attached with 2 bolts.
The PCV (Positive Crankcase Ventilation) valve on a 1996 Ford Aspire is located on the valve cover. It is typically found near the rear of the engine, where it connects to a rubber hose that leads to the intake manifold. To access it, you may need to remove any surrounding components for better visibility and reach.
The idle air control valve in a 1997 HOnda Civid LX is located on the throttle body. You will have to remove a few screws and two coolant hoses. The process is not that difficult but the it may be hard to get everything apart.
In a 1995 Ford Aspire, the valve lifters are located within the engine's cylinder head, beneath the rocker arms and above the camshaft. To access them, you'll need to remove the valve cover and possibly the rocker arms. The lifters are typically hydraulic and sit in their respective bores directly in the head, allowing for the adjustment of valve clearance as the engine operates.
use a PID controller
remove it from the engine
I have a 1994 ford aspire, just cleaned the EGR valve last week. it is located just to the left of the #1 fuel injector and the passenger side of the fuel rail.
