Question about Lexus Cars & Trucks
Posted by Anonymous on
Every body jumps straight to plugs and wires , when in fact the problem is more associated with an injector problem, dirty injector/s , low fuel pressure and pressure regulator faults take it to an accredited service center and have the code explained

SOURCE: #5 cylinder misfire
I have a corolla and had #4 cylinder misfire also diagnosed at autozone. After changing the spark plugs, problem persisted, along with the same error code, so they recommended changing the spark plug wires, and that is what fixed it. I would have changed the rotor cap too, but was low on dough. Glad that was not the problem.

SOURCE: rough running, erratic spark
Run a compression test on the cylinders.If reading is low on any drop a little engine oil into the pot. If compression rises you have compession ring problems. Remove all plugs before you try this and place leads away from engine.

A flashing check engine light is a critical indicator. That usually means that something went wrong that will damage the emission control system... and that is usually an ignition issue. First off, the OEM plug your car calls for is an NGK irridium... NOT BOSCH and not anything with more than 1 prong. Those NGKs are like 2 bucks and they are the proper plug. Make sure you have these plugs and make sure they are gapped to .028. Next, my suggestion is put all the new stuff on again. Drive it to autozone and have them delete all the codes. Drive it around until the check engine light comes on again, then immediately go back and read the codes. The ECU is smart enough to know which cylinder is misfiring. On these cars, I think they have three banks of two... meaning one "coil" inside the coil pack operates two of the cylinders. So if you get multiple misfires, it's the coil. If you get one misfire it's probably an individual plug wire or plug. Good luck.

SOURCE: No spark from coil pack
The most common reasons for them going out are not using dielectric
grease properly when installing, and from washing your engine.
I believe this was a huge issue with Volkswagen vehicles

These have a magnet on the cam sprocket, these magnets tend to fall out of the little plastic retainer. If the coil pack is good, and the ignition module good then it will prob. be the cam sensor pick up magnet. Unfortunately the timing cover will need to come off in order to access the gear. While all of this removed might as well replace the timing chain. Before tearing all this down have someone diag it to check the pulse width of the cam sensor, if you have no pulse then the magnet fell out. You may further verify by pulling the cam sensor and turning the engine until you can see the magnet or where it supposed to be, through the hole where the cam sensor goes.
