1993ES300x

i want to change my spark plugs and wire because the car just started shaking .. but the RPM is between 850 to 1000 on idel and a little higher(150more) when push on Drive.. and when i push the gas , the car shakes a little more. all i change since buying the car(2 months ago) are, the PCV Valve, flush trans and engine and put a bottle of STP fuel injector cleaner. the car started shaking two days after changing the PCV and fuel injector. so if anyone could help me with this. thank you.

car has 200K miles, it's said the engine was swap . so only 100K.

i see there's a LS DIY on spark plugs. but on a ES300, the back spark plugs are soo hard to change, i can't even see one of them that's located in the rear of the engine. and plus the wires are stuck in there i can't even pull it out (this is a sign of how badly the car was neglected, right?). my hands aren't small enought to reach back there. so if anyone can give me tips on changing the rear spark plugs. and what type of tools. please do. and if they can write up a DIY .. PLEASE DO!!!..

back plugs arent that hard to change.

the pass side one you can get to with an extention and a spark plug socket and a ratchet. the drivers side you get to from just around the intake or under the EGR if ya got room, the middle one, a spark plug socket, extention, swivel, extention and if that isnt enough, another extention, swivel and your there. ill have to see if i can get pics today and post them i do em at work in under a half hour usually

You definitely need various extensions to get to them, I didnt need a universal joint socket though.
Mark and move some of the hoses in the area and you should be able to get at them.

I moved around 3 hoses back there. You might find someone with very small hands to help.

the universal just allows you to ratchet from up top, above the intake. if ya wanna ratchet from underneith the intake, no swivel, just extention and socket and wrap your arm around the intake from pass side with left hand, while standing at pass side fender. thatll work.

I got alot of little nicks and cuts when I did the plugs, next time, if there is one, it'll be alot easier.
The lame part was that the socket I had from Craftsman wouldnt fit over the darn plug. So I went to Wal-Mart, bought a cheap no name socket set just to get the extensions and it came with a spark plug socket which fit perfectly over the plugs.

Since the car is around 200K miles it about time you change the valve cover gasket, it should come with the donuts for the spark plug seals as well. So what I did was buy the gasket kit, new plugs, new wires and some cleaner for the Throttle body. Just remove the throttle body, remove both valve covers, change the valve cover gasket and clean the throttle body. Once the Throttle body is remove you can easily change the spark plugs and wires. OHh and the PCV valve should be easy to get to once the Throtle body is off.

When I did this, I have one plug that I can't find where it goes. The plug/harness is white and there are two wires. It's part of that thick cable that comes out from where the ECU would be. It's kinda along the firewall. Does anybody know where it goes or can anybody look on theres.

A picture would be nice, there are a lot of connectors in there
