After months of the car only producing 0.5 bar on and off compared to the 1.1 bar it normally runs. It is now fixed!!

I have a 95 wrx, tdo5, pp chip, hks IK, 3 inch decat and system, tried looking for fault codes, replaced bcs, PES, and MAP sensor and still the problem occured. some days i would get normal boost other days just 0.5.

As it happens a new Tesco opened up near my work and i have switched to Tesco momentum 99 and it has never gone back to 0.5 bar! what a result.

I hooked up a temp knock link and guess what no knock. Went back to bp, morrisons and knock is detected.

I gather the car lowers the boost automatically to save det? back on tesco fuel and jobs a goodun.

When I spoke to morrisons they gave me a note saying their fuel was a bio fuel mix and even though it doesnt say on the pump what ron it was, the note claimed a mixed fuel gives......94 RON

don't rate the bp ultimate either, and theres not a shell near me for 30 miles.

anyone else have problems like this as well?

 

yes bp ultimate is not good stuff.

Esso 97 is not bad, Tescos 99 better and shell 99 v good if you can get it etc.

Lucky the knock control works else you would have lost the engine

Hi did you fill up at the tesco in westhill? I went to Inverurie an they don't do it. Was in Ellon lastnight and they were all out of momentum. Glad the car is running smooth now.

Tesco are a bunch of *****. Their customer care is second to everyone.

Ours has Momentum when it can be bothered. Other times, none, no rewasons given, no apologies.

I won't use it now.

 

glad to hear its running nice and smooth again, its mad how fuel can cause such a problem.

 

New Tesco Banchory!, Westhill has it as well.

Im ordering a new fuel pump and filter as the note from morrisons spouted some crap about "particulates present in fuel"

I still cant believe they mix upto 40% bio!!

 

shell v power all the way, it worth the travel

 

Fekk me Peter, no wonder she was pulling the timing, and like JGM says, good job the KS was working properly.

94 RON What fekkin decade are they supplying!!


Anyhoo, glad you've sorted it.

 

Tesco's in ellon have a habit of not refilling up the 99 when the petrol deal is on(5p off a litre when u spend xx amount in sotre) as it loses them money. i would imagine its the same for all the tesco's in the aberdeen/shire area!!!
