Hello have a 99 camry 2.2 auto. Been noticing a little lack of power when taking off. I changed the plugs and wires a round 60k miles ago. Im not sure on the fuel filter. Transmission fluid has 60k and still looks clean.

"butt dyno"; I'm stealing that one...

"Has no distribution" it might not have a distributor, but it has in igniter, which does the same job of spark distribution, so it could be part of the problem.

sounds like you need to do what I call a 30k mile tune up. seafoam the intake, egr, tb, iac, check for vacuum leaks, seafoam in the tank for injectors, plugs and wires as they're due, fluids and filters including trans which is 30k overdue, and then you can go from there.

i give the same advice to all who report similar problems. plus, get a haynes and voltmeter if you don't already have them as they'll be helpful too for the next phase which will entail checking the sensors for proper resistance readings such as the cts, iac, maf/map, etc., and checking the vacuum hoses for leaks using a dollar store cigar.

I dont do the seafoam unless the O2 sensors need to be replaced. even tho seafoam says its safe for sensors, sensors arent designed to be used with nothing but gas.


So, when they need replacing, Ill wash down everything and let the engine get cleaned, then replace the sensors when its cleaned. Theres too many stories of sensors going bad after a cleaning.


Lets see this engine to see if it has a distrbutor

"I changed the plugs and wires a round 60k miles ago". ok... was going by what you posted.

as far as seafoam hurting the sensors, you could be correct but i've used it on every toyota i've owned in the last 10 years from a 94 to an 06 and never once had a problem of any sort using it in the intake, through the brake booster, and in the tank. dunno what other guys are doing but used as directed, it works great.

as far as taking it to a shop "to clean the throttle body and to cpean the iac and ect", there again, that's just part of DIY on these cars. try it and save some bucks. (hint, the ect doesn't need cleaning - it needs to be ohmed out using that vom i mentioned you need to look into purchasing as there are several sensors and vsv's that need to checked on these cars periodically, including the o2 sensors).

let us know you fare.

Thanks i will look into it. I did forget to mention the car spun out on the freeway and when it did the front bumper swiped against the center divider wall and bent the frame behind the bumper. Had it fixed where it looks decent had the frame straightened out. But ever aince after that the car lost power after that.

Go with the code clue first.... p0420 = cat not working right...

- you got into an acident on a curb, this could have crushed your cat matrix causing a clog or ineffeciency

- a clogged cat = reduced power which matches your symptons

go with the simplest guess first... a clogges cat is the same as stuffing a bannana down your tail pipe...

once the cat matrix gets loosened or breaks apart due to age and/or collision, it can all 'bunch up' in 'one spot' inside the cat and act as a restriction to exhaust flow...

A clogged Cat will cause a loss of power. I had one on an old 1987 200sx Nissan. It really only showed itself at the higher rpms though, but once that CAT was replaced, it made it a different car. My Camry also feels a bit sluggish, but I am unsure if that is just the way it is for that engine. I have done all the maintenance on the car. I mean everything has been done. Fuel filter, plugs, wires, all gaskets, egr, throttle body cleaning, etc. No codes stored either.

Theoretically, yes. But my Camry's valve stem seals caused it to belch a big ol' cloud of blue smoke for ~10 years before I replaced them. It was using a quart or two of oil between 5k mile OCI's. It went to zero after replacing them. Never had a problem passing emissions.

Just saying, you should replaced the guides as well. Seals rarely fail unless theres play in the guides.. If theres play, even new seals wont stop the leaks and youll have to pull the head all over again.


But, if you get the head serviced, might as well spring for a 3 angle valve job, deck the head 010-015 and get a bit more compression and a touch more performance.


I would even take the head home, put some sanding barrel cartridges on a drill and smooth out any cast marks in the ports. The drop it back off to the mechanic. (cost: 20.00, better flowing head + more power)

The head is where the power is made, so while its off, might as well clean it up and squeeze more performance out of it.

OP.. Had an old miata with frozen oil rings... the oil would enter the compustion chanmber and come out as blue smoke... the cat matrix failed prematurley due to this... presumably the hot oil baked on the cat matrix cuasing it to fail... as someone suggested, bang on the cat to see if you can hear loose elements inside... you are getting a bad-cat code, you're burining oil, and you're down on power... so a bad cat is a good logical starting point...

cali cats are expensive as you know -- a carb cat can be welded on for a cheaper price.. bolt on carb cats are more expensive...

I did a quick reach under the car i didnt have a jack. But barely reached the pipe to the cat and shook it and didnt hear any rattling inside the cat but i do see the flange where it bolts up to the cat looks like flakey rust. So when i do replace it right i gotta get a new flange welded on. Tomorrow if i can i will jack it up for a better grab i also hit the cat too sounded solid didnt hear anything either could be full of crap. Anyways thanks

We are planning to drive the car to wa and back in july. I saw a guy parting out a camry 98 to 00 and he wants $100 for a used cat. I also was checking out millers cat and they dont have a camry for an option on there but then again i dont want to put a new cat if its gonna get clogged again. I think 100 too much for a used one. What do you guys think?

Valve guide seals


Which means the head need to come off for new guides and seals.

So youll need a new headgasket as well, plus coolant, and oil change since water will probably fall into the oil..

Yea, to do it right, it all adds up.

Yes.
