Engine Electrics, possible mis-firing

[Boomin33]

So I take my car to the RR today and it's running super sweet.

 

did give it a bit of of welly when I got closer to home, but don't think that something suddenly broke? There is a sound of what appears to be a boost leak coming from the gap between the engine and the cabin. but couldn't find any obvious disconnected or perished hose.

 

Problem:

Basically sounds/feels like it's got a subtle misfire. Instead of running smoothly, sounds more like a rumbling sound.. all through boost/acceleration. tbh the electrics/wiring is probably the weakest link in my car :(

 

 

I Did a basic check on coil packs and connectors and nothing looks untoward. I'm going to give it another go tomorrow as I have to find the cause pretty quick if I'm going to go to JapFest on Saturday a.m.

 

Any Suggestions? Anyone experienced Zed Mechanics near Berkshire that would have a look at it... if I brought it by tomorrow??

 

TIA

Bizzare! just Bizzare, if you didn't take into consideration I've got a tempermental car here....

 

Fire it up this a.m. after checking all the hoses, connections etc... runs pretty rough to start and then settles into yesterdays rough & rumble attitude.

 

Even gives a couple subtle backfires as I'm pulling onto the back roads. Continues with the little gurggles and rumble run... so I figure I'll check boost. So I punch it to 1Bar.

 

Get up to 1 Bar and think to myself "Well, that felt pretty good"

 

Hokus-Pokus....make a wish, sir... ....instantly all back to normal !!???

 

Boosting sweet, purring like a kitten at idle, as well as on boost... well lets say a kitten the size of a train.

 

generally running sweet, so I parked it up!! :).

 

** I know I'd be daff to think it's all sorted now.... but I'm not touching her until the a.m. and driving straight out to JapFest ( with a load of electrical tape! )

 

any thoughts.?

 

 

**btw- thanks for the offer VodkaShots.. appreciate it, much.!

Well hope it all goes well, and if you need to pop it into me, I've got the free version of consults at the moment running, I know it doesn't give all the functionality but at least it let's you read any error codes it throws up, and monitor things

Got up at 5:30 a.m. on Saturday to try and sort it. Coilpacks off, checking all wiring etc.

 

Sorted!! it was a Bad connection on one of my coilpacks.

 

Got the Zed running sweet, got to Japfest 20 minutes before my Track briefing... truly awesome time.

 

Car pulled like a beast. very tough to keep tyres on traction in 3rd... it just wanted to constantly drift.... or was that just me? ;)

Yeh those poor tyres,you drove the ass off that car at Japfest,nifty driving mate i must say.Some great sideways action.You done much track driving,looks like you have,or did you get loads of practice in the states with powerful v8 motors :rockon:

[Boomin33]

Hey Jimmer... I actually ripped some tread off those poor tyres... literally peeling off from near the sidewall !!

but... they were freebees that came with the alloys I bought on ebay. Continentals at that! I cut off the dangly bits and got back home fine.

 

yep... have done quite a bit of sideways driving in my years ( grew up in the snow ). and a few track days in the UK. This was the first ( of many, hopefully ) in my Zed.

 

I actually thought it was pretty twitchy driving and was a little embarrassed I didn't make smoother transitions out of the slides. I also got told off when I left the track :)

 

There's a good video that I found, that I just posted... but unfortunately he fell behind before I really got going ;)

 

 

** let me know if you have any opinion on the black puffs out of my left bank... I just posted a thread in "helps and advice" TIA
