2002 4cyl engine noise....TSB help???

see if you can find a knowledgeable independent mechanic that specializes in Toyota to help diagnose it. fuel treatment or higher grade fuel would be for pinging the noise could be from the transmission could be a loose heat shield on the exhaust system could be a problem with a sensor, not signalling the ecm correctly on acceleration (even something simple like a disconnected wire)

If your car is under warranty now, then you should take it to the dealer and have them fix it. Taking it somewhere else doesn't make sense. Even if you take it in and the dealer can't find a problem, you now have a record on file of your problem. Then, if it shows up in the future you will be covered, even out of warranty.

TSBs are available from two sources.

1. The NHTSA, that charges by the hour, for duplicating services and copies, at:

   NHTSA is the only source that?s up to date. - and -

1. Alldata, that charges by the car, at:

   Alldata does not have all of the current year (2005) TSBs,until later. It has no 2006, yet.

Could you expand on "funny noise"? And is it worse when very cold?

i posted about it almost a month ago and someone gave me a link to

we haven't had any real cold weather yet but after running another can of BG44k thru the tank the problem seems to have cleared up a little. the noise (as someone else helped decribe it) sounds like bottle caps bouncing around. it might be *Pinging* to others. i got the car from a senior citizen so maybe there was some carbon built up that the fuel additive has cleaned up, but when driving it at normal around town speeds it has a tendency to show up again. if i drive the car hard (accellerate hard and drive fast) it goes away for a while but after resuming normal casual driving it has a tendency to show up again. i use the same gas EXXON 87 oct. in my '99 Camry and never have a problem w/ the performance of that car and this '02 only gets about 15-25 miles a week put on it. i live close to where i work (about a mile from my home) so i usually ride my bicycle when the weather is nice and we use the car to shuttle the kids to soccer, food shopping, church and other around town stuff only. my '99 is use for the wife to commute to work which is about 160 miles round trip 4x's a week and that car has 157k miles on it. she has used the '02 (has about 25,500 miles on it) to go to work a few times and says the car runs great and it does, there is no hesitation what so ever, it idles real smooth and there is no hesitation when the gas is mashed to the floor. sometimes it just sounds like the old (60's-70's) Volkswagon Beetles.

thanks...

Mostly 'cause I got tired of seeing this thread :>0, I broke down and looked through the Gen.5 TSBs for you.

Some "shudders," some surging, even a "thunk" from a suspension problem, but nothing like you report....There is a heat shield rattling, but it doesn't jibe with what you report.

If I can bother you, where can someone get access to tsb?s, other than thru the dealer? Is there any sites that will allow us to view them?

in section 1.3 of the faq there is a link....I posted this to him before, but for some reason he never looked at it.

every time i try to open it i get a pop up messsage that reads; "Cannot open file; it does not appear to be a valid archive."

that's why i've asked the message again. thanks for your help though,

mike........

If you get the error message "Cannot open file: it does not appear to be a valid archive" you should delete the file from your harddisk and redownload it.

i tried that twice and still got the same message.
