Hi forum members.
I will be changing the spark plugs on my 1995 Camry le wagon since it may help with the vibrating when stopped at a light. The new EGR vacuum modulator I added today didn't help with that...although I have only driven it around the block and maybe it needs a good freeway run to clear out any remaining debris.

The sparks and wires etc are about 9 months old and replacing those back then didn't help with the rough idling when in gear and stationary. The air filter isn't dirty after being replaced a year ago but should I replace it anyway for possible help with smoothing out?

My last mechanic broke one of the rear metal corner snap 'things' that hold the top of the air filter cover on tight. Would only having the three of them locking the air filter 'hood' possibly cause a rough idling issue.. escaping air? Seems like it would be too minor.

About new spark plugs, should I go with what Toyota recommended after adding my VIN #?

Below are the spark plugs Toyota recommends for my vehicle......

• ==========================================

I have read that some Camry owners swear by twin-tipped iridium spark plugs yet many others say to stick with simple Denso double platinum # PK20TR11 , or NKG iridium ones. Not sure if getting the Toyota brand will make a positive difference.
Apparently neither brand needs gapping.

One more thing please: when I sharp right turn and for the last week, there is a squealing coming from the front (possible wheel) area. I am also now hearing slight clicking from the DS front end when I turn right. Could all that be related? I'm not losing power steering fluid and it doesn't smell burned

Any suggestions please.
Thank you very much.

 

The materials used to make the plug make it last longer. See link below:

Unless the plug is defective, worn out, etc it should perform as designed. The standard Camry designated plug should last at least 60K miles.

For the clicking noise, make left and right and sharp 360 turns at low speed and listen for noises.

For squealing noises if the steering wheel is turned to the stop the power steering belt may squeal as it slips on the pulley. The belt is too loose.

Rough idle can be from air leaking into the engine intake AFTER the air filter.

 

Thank you very much for your response and link to spark plugs. Certainly much cheaper on that site.

Will need to check for air leaks again once it stops raining. Last week I sprayed soapy water over the hoses and there was no change in revs or any leak sounds or bubbles. Maybe the mechanic can do a compression check. He also suggested that replacing the PVC valve may not help much with the rough idle since there really is no extra oil consumption, or any misfire, blue smoke from the exhaust (just a little white smoke upon staring up) nor check engine light being on. Easy enough to change though.

Will check for front end clicking noises.
I appreciate your help!

 

Hello again forum members and thank you for your help in the past.
I have another reach-out please, for suggestions regarding spark plug changing on my 1995 Camry le.
Because of twice recently the engine not wanting to turn over or stay on until two or three more attempts (and when on some grey smoke is seen from the exhaust which clears in a few minutes) I purchased some apparently really good spark plugs to do a change out.
I was told this should also smooth out rough idling in gear.
This morning I have the spark plugs, the spark plug extension tool, and the 5/8th socket with magnetic head that I bought less than a year ago.
I managed to get one spark plug out, which looks according to the picture below in decent condition I think, and replaced it - but for the life of me the other three I just can't bring up. I unscrew over and over and the plugs 'felt' loose so I'm thinking perhaps the magnetic head has lost some magnetism, however the plugs should come out regardless.

Nothing I have otherwise is slender or deep enough to go in after them, so now somewhat worried I just screwed each three back down.

Actually even changing one made a bit of a difference in the idle and because of so much rain and cold weather recently here in Portland, maybe that's the reason for a couple of difficult start-ups which never occurred before even in harsh weather, but the Camry this time I hadn't used in 3-4 days.
Can I, without fear of losing it, add 'somethin' inside the magnetic socket heat to grab the plugs better?
Sorry for this juvenile question for a simple procedure but I did persevere but got worried.
Thank you for any suggestions.

 

There are spark plug sockets with a built-in rubber grommet that will grip the plug to allow it to be removed. Or get a section of stiff rubber hose or tube to push over the insulator to grip and pull it out.

How about the distributor, rotor, etc.

Read up on cleaning the Intake Air Control valve (IAC).

 

Thank you toyomoho, good to see your name and for your response.
Good ideas which will be put to good use this morning once it warms up here as far as replacing the rest of the spark plugs.
Thanks again.
