losing power

losing power

okay so i ignored it the first couple of times but it is starting to worry me now.


sometimes when im stopped at a stop sign and i accelerate, my car will sputter for a few seconds..it feels like its losing power and i can hear it sputtering the exhaust out. but then i rev it up some more and eventually runs alright again. it does it sometimes too when im slowing down and im almost at a stand still or this one time when i was on reverse to parallel park, my rpm was fluctuating.

any ideas?

when was the last time you cleaned your maf sensor?

since i visited tweak in late march

i replaced them around 79k and i'm at 108k now. ngk iridiums. are they due for replacement?

i replaced mine every third oil change, back when i had my corolla.

you're not throwing a code?

oh wow, I'm almost due for an oil change (about 1k miles cus I do it every 5k since I use full synthetic).

am I alright to wait till then or is this something I should handle asap?

I really hope it is just spark plugs. and vortex, thats exactly what i am experiencing...when I get the rpm's up there it doesnt sputter anymore.

so I should get new plugs every 3rd oil change? I didnt know the interval was that low. lol

my motor was pretty narsty by the time i was up to that kind of frequency. i didn't take care of it.

dont forget to change your spark plug wire if you havent done it yet.

2001 Corollas don't have plug wires.

Depends on what replacement plug you have currently - the OEM Denso Iridiums are spec'd to last 120K miles. I changed mine at 90K and they still looked OK - but decided to change them anyway. Went with NGK Iridium IX plugs - smaller electrode diameter than the OEM ones - those plugs are only spec'd to last about 30K-60K miles.

Also, double check that your Coil on Plug modules are OK, not cracked or burnt or anything. Could be a case where one of the plugs got a little loose as well. I'd take a peek when you get a chance - depends on how quickly you can cover 1K miles, but I would recommend doing some quick diagnostic work. At the very least - pull the plugs to read them. If they are toasted - you can pickup another set of plugs and replace them when you change the oil.

change your plugs/wires again, clean your throttle body, you know........i could just talk to you on aim about this...

has anyone tried ngk oe laser iridium plugs?

I have a set sitting on my box wating for install... will report maby tommrow night...

yeah about that..

yeah they are good. they have long life. i wusually pull them out to inspect them when i had nothing to do and over a 4 month period they were pretty clean. plus the butt dyno saw better response
