I have been noticing some high pitch clinking noise when accelerating in high gear (5th) at low speed. The noise is not loud but noticable, Should I worry about that? I think it's been like that since I bought the car brand new, but recently just curious would like to ask the experts here.

The car is 2000 TypeR with 45k miles.

 

any mods to the car?

 

What Octane gas are you using?

 

Run a higher octane fuel, reset adaptive values once you put at least a 3/4th or more tank of 93 octane fuel into vehicle.........reset adaptive values means disconnect negative battery for at least one minute, then reconnect.

Engine is pinging from low octane fuel...have u adjusted timing at all?

 

The car is still all stock, and I use 92-93 octane all the time, except a few time that I put 90 when I could not find anything higher but it was long time ago.

The thing is that it only appear when accelerate at low speed with high gear... And it wasn't a loud noise at all.

any suggestion?

 

How low of an engine speed?
Are you doing WOT runs in 5th from 1500rpm?
If you are ...

 

Not exactly that low but 35-40mph range..

 

So, about 2200 rpm?

Learn to downshift!
Its only a 1.8 L motor, not a corvette.

 

I have been dealing with the same thing, accelerating in a higher gear, part throttle at 2.5-3.5k rpms. I have narrowed it down to either a faulty injector in cylinder number 1 (just by reading plugs) or the dealer somehow re-programed my ecu after they replaced the block. (because it started shortly after that)

I have gone down to 1500-2000 rpm in fifth gear but thats when I'm saving gas

In your opinion this is normal then?

 

I usually down-shift, but sometime you know you just need a little acceleration.

Any thing I should be worry about?

I have short shifted at times and found myself in 5th doing relatively low speeds in town.
However, I have not experienced much if anything in the way of knocking or pinging.
I do use 93-94 octane gas regularly, though.

 

I'm not sure... it seems that after some high rpm heavy acceleration and then when I shift back to cruising and some light acceleration in 5th, it is more noticable.

 

EGT temperature gets high on 5th gear...

 

Mine has done it on and off since I bought it. A little pinging never killed anything. *shrug*. I'm not 100% convinced that's what it is, but it does follow the symptoms.

It's handy if you're smoking and drinking a soda, you don't have to reach for the shift lever when making a left turn. I am teh distracted driver.

Ping on!

Que?

If you're pinging, EGT would go down... what does gear really have to do with EGT?

5th gear being coincidental with highway driving, when you're stoich and putting out a reasonable amount of power, that's why you'd see higher temps. 4th gear under the same circumstances would be about the same EGT.
