I didn't see any instuctions posted for the 6 cylinder Camry.
I changed the front plugs already, do I have to remove the intake to change the back 3 I got the first one out but the other 2 are unreachable.

This is an ignition error. that could one of several things wrong. since it is noted in Bank 1 it is a problem with the right side of the engine Cylinders 1, 3 or 5. located under the intake manifold (close to the firewall)
1. Fouled plug (cylinders 1, 3 or 5)
2. Bad ignition Coil (cylinders 1, 3 or 5)
3. Wire fault to Coils (cylinders 1, 3 or 5)
4. Fault with the O2 sensors (Right side bank 1)
1. Start by checking /changing the plugs. You have to remove the intake manifold to get to plugs (cylinders 1, 3 or 5). if the mileage is high and they have not been changed, then its probably due.
2. Inspect the coil wires for cracks or faults.
3. Swapping the coils cylinders 2, 4 & 6 for cylinders 1, 3 & 5. if the fault changes to bank 2 then you have a bad coil on 2, 4 or 6.
You'll need to remove the oil cap and the 6 bolts holding on the engine cover. The front 3 spark plugs are pretty easy to replace. You'll need to unplug the spark plug wire from the coil and disconnect the electrical connector. Unbolt the 2 10mm bolts holding the coil to the valve cover. Twist the coil and boot back and forth and pull it out of the cylinder head. The spark plug is down in the head, you'll need at least a 6 inch extension with a 5/8" spark plug socket, a telescopic magnet will help get the spark plug out of the head. The back 3 spark plugs involve removing the upper intake and throttle body, unbolt the bracket to the throttle body, and the bracket bolted to the upper intake manifold. on the back side of the engine. Remove the tubing from the throttle body to the air cleaner box. Unbolt anything else bolted to the upper intake. Unplug electrical connectors to the throttle body and any other electrical connectors on the upper intake and remove the upper intake bolts. And move the upper intake out of the way, there are only spark plug wires on the back 3 plugs. Twist and turn each boot to aid in removing the boot from the plug. I would get a new upper intake gasket and consider replacing the wires at this time also. There are actually only 3 spark plug wires, so for what is involved to get to them, I would replace them. I have found alot of the wires will arc to the upper intake manifold.
you cannot change oxygen sensors from front to back as they are 2 completely different units doing completely different jobs
the problem is water in the electronics and you use a dewatering fluid ( wd-40 or like ) to disperse the water not starter fluid
First, you didn't mention which engine your 1994 Toyota Camry is equipped with. (This is really MUST-KNOW information if you want help with fixing your car.) There is a 3.0L V-6 engine and a 2.2L 4-Cylinder engine. Two TOTALLY different animals! I'll just take the extra time to answer for BOTH of them....
If your Camry is equipped with a 3.0L V-6 engine, You cannot find the spark plug wires because there are none, That engine is equipped with Coil On Plug (COP) ignition. The coils on the left bank (the side of the engine near the radiator) are located under the plastic cover on top of the engine. The coils for the right bank (the side of the engine near the firewall) are located under the upper intake plenum. The plenum MUST be removed to access them. (this is also required to replace the spark plugs.)
If you have the 2.2L 4-cylinder engine, the wires run down the center of the valve cover and the boots go down through the valve cover to the plugs. The other end of the wires attach to the distributor cap at the rear (drivers side) of the engine.
you have 3 in the front engine head, you will see 3 spark plug wires accross the front cylinder head. The remaining three are located in the rear cylinder head. You must remove the intake manifold to access this.
You didn't specify whether you have the (4) cylinder or the (6) cylinder engine.....
I have a 2004 Hyundai Sonata 2.4L 4 cylinder and I just changed the spark plugs in it. I believe that the 2005 2.4L engine is the same.
To locate and change the (4) spark plugs on a 2004 Hyundai 2.4L 4 cylinder engine:
Remove the (4) 12mm bolts from the decorative plastic engine cover. Remove plastic cover from engine and place it off to the side out of your way.
Standing in front of the car, the (4) spark plugs are located laterally (left to right) in the recessed area underneath where the plastic engine cover was removed.
Note: This engine has (2) coils....They are located above spark plugs number (2) and (3) from left to right.
Starting with the fist spark plug on the left: Remove the spark plug cable by pulling straight up on the insulated connector. Using a spark plug socket, remove the old spark plug and install a new one in it's place.
To access the second spark plug from the left, remove the electrical connector and the spark plug cable wire from coil number (1) and then remove the (2) 12mm bolts that secure the coil to the engine. Spark plug number (2) is located directly under the coil. Lift the coil straight up removing the insulated connector from spark plug number (2). Using a spark plug socket, remove old spark and install a new one in it's place.
Repeat same procedures for spark plugs number (3) and (4).
Note: If you have the (6) cylinder engine, the front (3) sparks pluge are readilly accessible but in order to access the (3) rear spark plugs, you will have to remove the intake manifold
Well, if you have the 6 cylinder, there are 3 02 sensors in that car.
One on front manifold, one on back manifold, and one in the center pipe.You changed one, good idea to change the other 2. That is if you have the 6 cyl.
hey thanks for bringing me up to speed. ive been working on many other problems but with your great explanation i remember. we need to check the compression on that cyl. and compare it to the compression on 2 other cylinders your choice. but before you do this get a can of carb cleaner . and with the car idling spray around the intake manifold in the area of #6 cyl. what we are looking for is a small vacuum leak that would also act like this. with the engine idling and spraying around the intake the engines idle sould not change and if it does when you spray you have an intake leaking. let me know how it turns out. later paul
