This has been happening for a couple months on my Subaru, drives  great no issues and done quite a bit of servicing recently on the fluids and filters, but when driving sometimes I put my foot down nothing happens and even if I put it down almost all the way, but then it suddenly takes off. What does this sound like? I always fill up with 98, everyday at high speeds so I don't think it would be something like a clogged injector. Maybe a fuel pump failing?

Mysterious lol? 2001 impreza. Maybe throttle body needs a clean? The car is driven well I don't floor it or do any stupid shit. I wonder if it was that time I messed with the throttle position sensor, but I did put it back to normal.

it might also be an issue with the gearbox

It's an automatic, and it does shift smooth but every day after work it does shift a bit funny on this road I always drive on (just a normal straight road. I might be ovethinking it), when I changed the transmission fluid, the filter barely had any debree inside it like a couple of specs lol, it was also red the fluid so didn't look contaminated. My mechanic was surprised when he opened it, there was no discolouration.

i have an sti these things are full of problems...clean or replace maf, clean crank angle sensor, make sure your plugs and wires are new. replace your 02. make sure you have a strong battery connection, ive seen bad connection cause all kinds of misfiring or  weird issues with these cars.  you should know by now to post a what year, make, model, etc to get better help. i personally cant stand the subaru forums bunch of kids and wierd mates on them so i figure crap out myself, but go through some pages on the butt buddy subaru forums sure you will find some info to get the old girl some help mate.

Ok, thanks for the feedback. 02 could use a replacement lol the light does pop up frequently lol, wires and spark plugs changed not too long ago, I'll see what I can do.

Before you replace the o2 sensor, replace your fuel filter, then check your fuel pump output and pressure. Check ALL vehicle ground wires. Cleaning all the ground connections won't hurt.

i took it to my mechanic i need a new knock sensor, there was a code for a throttle position sensor but apprently its old. Suprisingly nothing for an exygen sensor. I wanted to ask do you think its a bad idea to buy a 20$ one from ebay as opposed to a 95$ from a retailer?

I don't recommend ebay LingLong brand anything, when the genuine stuff is outrageous price, I buy from Burson or Repco or any other place that will refund my money. Also if the part f**ks up you can jump up and down and shout at the human who sold it to you.

So how much was it from : any other place that will refund my money. Looking up one price on the internet is not shopping around for the best price bro.

i saw 20$ ebay ones have a 5 year warranty.

Found one of these in a BMW once, it was so badly calibrated it didn't do the job, but not out of ecu range so didnt throw code.

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
