HELP!!

Last night driving home I gave my car some beans pulling out of a junction and the car spun all 4 wheels on what I think was some ice or deisel. The car hit the rev limiter, I changed up into 2nd and then the car felt really sluggish all the way home.

At lunchtime today I was driving home to check whether my UK300 spoiler had been delivered, (which it has ) and the car still felt a bit sluggish so I opened her up going up a hill on the A48. I hit about 85mpg in 4th when the car hit it's usual flat spot.

The car felt awful and then I noticed the "Check Engine Light" was flashing at me. FOOKIN HELL!!!! I let the car drop to 40mph immediately and then took it really steady all the way home. The light went out after about 30 seconds and hasn't come back on since but the engine still doesn't feel great.

I'm due back at PS on Friday anyway but I phoned Rich straight away and he thinks it may be over-boosting but said he'll sort it all out on Friday.

However, I am worried. Any ideas?

 

this is a wild stab in the dark but the engines can trip in to safe mode for certain reasons, however you know it had done that as opposed to just be sluggish

when my check engine light kept coming on on the uk300 CVC asked if the car was low on petrol as going up hills had been know to cause it - something to do with starving the engine!

all in all no help at all sorry Rich but i hope you get it sorted!

 

I don't think it's fuel as I have 3/4 tank at the moment. It's a fairly steep hill and the Impreza Owner's Manual does say to avoid steep uphill grades (amongst other things) if the light flashes.

Strange how it happened at the flat spot. When John drove it he did say it felt like a misfire, which the falshing light can also indicate is wrong with the engine.

 

take it easy rich never a good thing when the check engine light comes on,it could be overboost.is the engine any louder than normal,when my old scoob overboosted (due to me putting on a bleed valve)i blow two coil packs,you havent got coil packs but you can still wreck spark plugs and stuff.sometimes the car will go into limp home mode but if this was the case you would have no boost at all.

 

Could be as simple as Maf or a bad tank of fuel

 

I did fill up with Esso SUL last weekend, the 1st time I've used anything other than Texaco or Shell for quite a long time.

Still, it's more likely to be related to the flat spots I would think.....

 

All the other fluids OK Rich? Was it a busy station or could the fuel be as Sam says bad? make sure you take it nice and easy up to PS and hopefully they will sort it for you.

 

It could be what Sammy has said, a bad tank of gas but to be on the safe side I'd try to keep it off boost and just tottle along until friday.

 

OK........now wheres the spoiler pictures??????

 

Kev's helping me to fit it at his place tomorrow evening!

Thanks Kev!

I should have some pics up by the weekend.

 

sammyh if it was maf it wouldnt idle properly would it.

 

It idles fine and starts fine and the light hasn't been back on since but the car feel gutless.

It seems really unresponsive and seriously lacking torque.

 

The car will still idle with a f**ked MAF, but kangarooing can occur. The ECU learns to keep the engine running. Disconnect the MAF and the engine should die like John Wayne, if not then the ECU is compensating for the MAF, therefore f**ked MAF.

 

Maybe try an ECU reboot to clear any bad habits off there first, if you've been mapped on one fuel and are now runing another that may have something to do with it.... how much fuel have you in the car at the moment Richie ?? maybe you need to get you normal fuel back in especially if your having the map re-adjusted on it this week.

Just keep calm you will get there

 

You sure none of the pipes have come loose.

(bloody "Invalid link" error - no emoticons for me in this thread :-(

Anyway.

I've just got back from Powerstation and I'm well pleased with the results. The flat spots have gone, the acceleration is punchier and I have more power and torque! :-)

There wasn't anything particularly wrong with the car (and strangly no errors in the CEL history log, which Rich found odd).

He spent nearly 2 hours remapping it and found that I was suffering from some minor det in the mid-range but nothing serious. He did find that the "Main ignition map" and "Ignition correction map" were working against each other and probably causing the problem so he spent plenty of time remapping the ignition characteristics.

He also changed the throttle/lambda figures (not sure of the exact parameter) from 20% to 30% to try and improve my ****ty MPG's.

I've listed my last map and new map figures below, makes pretty interesting reading, especially the "Wheel power" figure :-)!

Before:
Corrected power = 258.3 bhp
Engine power = 255.6 bhp
Wheel power = 155.2 bhp
Drag power = 100.5 bhp
Max power at = 5805 rpm

Torque = 347.2 Nm
Max torque at = 3520 rpm

Now:
Corrected power = 261.2 bhp
Engine power = 264.2 bhp
Wheel power = 165.7 bhp
Drag power = 98.5 bhp
Max power at = 5795 rpm

Torque = 348.8 Nm
Max torque = at 3840 rpm

In addition to the figures, the torque kicks in sooner and he said he's managed to get it to spool up sooner.

All in all, a good result.

 

Brilliant Richie

Your feeling a little happeir with the car now then to say the least

Good improvement on all the figures to

 

Yeah, I'm well pleased. And I managed to get back in time to wash the car and wheels plus a quick bonnet polish!!

She looks stunning out of the window right now, (especially with the new spoiler ). Time to go and fill her back up with some of Texaco's finest!!

 

Good news, just a pity you had probs from the off. But with those figures a worthy trip

 

im pleased for you rich,now can we have no more of this silly talk about selling her now.

 

I give my sincere apologies to anyone I may have offended with my "selling" talk.

Especially to Daz, no offence. I promise to keep her until she at least has:

1x TSL Ti-phoon
2x colour coded side skirts
2x Morette headlights
1x decat downpipe
1x decat up-pipe
1x remap
1x STi blue interior

oh........and a minimum of 300bhp.

 

thats more like the rich we know and love,welcome back

Front mount + Bigger Turbo?????????

 

Subaru dust caps

 

happened to mine they told me it was the ecu shutting down ..... safe mode disconnect the earth wire for half an hour and it resets itself

 

Funnily enough I bought a set from eBay when I first bought the car, the anti-theft dust caps with the star emblem on them.

They worked too, nobody stole them.

However 3 fell off while I was driving. They were there when I left and I heard one fall off as I pulled out of a junction and when I got to the other end 3 had gone.

Waste of £10.

Next time I bought the chrome ones from Halfords for £3.50. They looked good........until some **** nicked them all.

I am going back up tp PS on 9 Jan. Looking forward to the "Quest for Torque".
