1997 toyota corolla exhaust replace

[ademelo]

I need to replace my entire exhaust system. I live in canada, so things ten to get rusty in the snow. What would be the cheapest and most efficient way to replace it? According to the internet, its very easy to do the repair myself, but im not sure where to look and what pieces to buy etc.

There are many placed online to get exhaust parts. But, shipping cost will be a big expense.
I suggest getting the parts locally from a parts store.
You will need the tail pipe, resonator,muffler,catalytic converter, any pipes not connected to those parts and all the related gaskets, bolts and nuts since they will be rusted and you may have to cut them off.

Experts,
Please, kindly enlighten me on what could be wrong with my 2001 Toyota Avalon as I observed that the car`s engine vibrates whenever the tachometer reading is around 700rpm (when the car is in idle mainly during traffick), at idle state or when I on the ignition, i think it should not be below 1000rpm.

Because of this problem, if i drive in the night i normally experience flat battery the next morning when i want to start the car (maybe because the low reading is causing improper battery charging by the alternator). I dont use the A/c while in traffick because the extra load on the engine brings the tachometer reading down more which may eventually trip off the car. When I made a full steering turn, it trips off the car.

It was not like this before, PLEASE, advise me b4 I go the mechanic.

Thank You

I would have your battery checked. A good battery will bring itself back up to charge if there is no load and it just sits for some time. You can check your charging system but if your battery doesn't have the amp reserve left in it it will sometimes not have enough cranking amps to start regularly.

you might want to check the operation of your Idle Air Control (IAC) valve. it should raise up your idle according to the load on your engine. If toy turn on the AC the idle should go up to support the extra load. It might also be the reason the idle is too low and lets the engine vibrate.

O the engine vibration at 700 rpm, it's possible that your engine mounts aren't absorbing and insulating your engine from the body. If the vibration seems to go away at normal idling rpm (like you said about 1000 rmp) then ley that go for now.

My car tends to overheat while driving. Once this happened at midnight while I was driving. When I opened the hood on my car to check the fluid level in the radiator it was putting out hot steams.

I called a mechanic. He told me it was due to a thermostat. They repaired it and it was fine for a month. But now again this problem is coming up? What should I do about it?

have you checked your coolant level?

Hi, everyone.
A friend of mine is got an RX 300 Lexus truck, 2007, V6, with 107,524miles on it. Ever since he bought the car as a used one, it has being consuming excess fuel. Though, there is no black smoke coming out. We have tried scaning the car without success, because the CEL only displays on the cluster intermttently. We have tried checking for vacuum leaks, but got nothing. The plugs, air filter, vacuum pipes, exhaust pipes and catcon are OK. Although, the MAF sensor thermistor was very dirty, and has being cleaned. I am awaiting feedback from him, what the effects of the cleaned MAF sensor had on the car's fuel consumption.
What do you guys think could be the problem?Why won't the check engine light come on, so that we can scan it?
Appreciate your helps in advance.

scan for codes. the check engine light rarely comes on for no reason. See what codes may be stored in memory. you may need to try a different scanner. Some code readers won't show pending or one trip codes. They will only show hard codes.

excessive fuel consumption is ambiguous. what has the miles per gallon that you believe is excessive? Fueleconomy.gov says that the 07 rx350 4wd was rated at 19 mpg combined average. I know that many people don't get the same mileage as the reported fuel economy numbers because of their driving conditions and driving styles but how far off are your consumption figures compared to the new ratings from back in 2007?

If there are no codes or any scanned values that are out of the ordinary, the computer is programmed and calibrated to give you the best of performance and mileage within EPA guidelines.

Use a scanner and drive the vehicle under your normal conditions and look at you fuel trims. Some O2 sensors, when they get older, will slow down their reaction times. They get some residue built up on them or may even get contaminated. Catalytic converters sometimes get clogged with debris, damaged or contaminated and reduce their flow. A dirty MAF will usually show up as a lean condition on the back end because of reduced airflow readings.

Thanks for the reply. We have tried scanning the car, but the check engine light won't just come up. It comes up intermittently.
So, what do we do now?

[carriedi]

try a different scanner, try scanning for mode 6. what kind of scanner are you using?
