good stuff. found this video on youtube regarding the clearance and tappets. I'm sure Toyota would just say replace the tappets and valves (if necessary) but maybe it'll help save some money. wish I had more input but I've never tried it
Ray, If you're still wanting to have an operational airbag than I would suggest leaving the OEM stock wheel on. The cars are crash tested with that specific airbag and even if the new steering wheel's airbag works it may cause more harm than good if it inflates. Not that I'm recommending it...
yes check the OBDII and see what (if any) codes it threw. If it doesn't help pinpoint the issue, start by pulling your spark plugs. The way a spark plug looks can give you a good indication of what might be happening inside the combustion chamber. Also check the ignition coils. Wear and tear...
Has the vehicle sustained any collisions or have you ever bottomed out reasonably hard? You would know if it was anti-freeze somehow coming into the cabin and AC condensation drips outside of the vehicle. Even if it didn't there's no way it would ever get that wet. It sounds like you have some...
pull the spark plugs and see if there's any damage to them. If you see any damage it may help you determine if a certain cylinder sustained anything catastrophic. once you pull the plugs use a flashlight to look into the cylinder. If you have a snake camera even better. you can check out the top...
just off the top check your ignition coils. The more miles and heat the more they are susceptible to malfunctioning or misfiring. I had the same lagging issue and it turned out it was coil number 4 on it's way out. replaced it and she's running like a champ! If you search youtube you'll find...
please change your oil as recommended by Toyota. The 1ZZFE engine is all aluminum (top & bottom) so overheating is the worst thing you can do to it. Recommended by Toyota is 5W/30. Most mechanics will tell you to stay consistent with your oil. If nothing is wrong don't change it. A Toyota...
it sounds like it could need a valve adjustment. unfortunately the 1ZZFE isn't the easiest to adjust because they have tappets. but what you can do is at least measure the gap between the cam lobes and the tappets. If you do a youtube search you can find videos on how to check tolerances. here's...
