As above, i'm trying to trace the cause of what seems to be a miss. It happens when the car is under load, ie when i put my foot down hard. If i step the boost up slowly its fine but when i floor it, it misses. Tried changing the plugs today and that didn't make a difference, so i'm hoping it will be a weak coil pack. Its a 93 wrx, so has individual coil packs for each cylinder. If anybody has one they know to be working fine that i could have a lend of to try swapping them about, that would be great.

 

I'm not sure if he does have a spare coil pack but try Dylan.

 

Cheers Ty. From some of the stuff i'm reading on here it may be a boost issue. Someone has mentioned to try the Nuetral Position Switch on the gearbox, sounds a bit bizzare to me but worth a shot maybe.

 

hi taylor try mr d i think he had some

 

I've got 4 over at my unit and you'd be welcome to try one or two if that helps you out. I've had similar problems on a few RX7's lately and it's turned out to be the boost sensor, if you drive gently it'll drive through but push it hard and it'll miss........worth a try
Dave.

 

had this problem on my last classic, done the usual things plug's etc even tried a new maf sensor in the end had to fit a hks FCD (fuel cut defender) sorted my problem out..

 

If i could borrow a coil pack off you that would be brilliant thanks Dave. Where is your unit and when would be best to pick it up? I'm going to the meet wednesday if thats easier?

Thanks for the reply Lee, hopefully shouldn't require a fuel cut defencer as its run fine in this state of tune until now, hoping its a coil pack.

 

No probs my friend, i'm there all week at Unit C1, Brittania Enterprise Centre, Pengam Road, NP12 3SP. Numbers are 07810 098199 or 01443 838104, just let me know if you are comming.
If it's dry on Weds i'll hopefully get down to the meet but if it's raining i'll stay home so i'll let you decide
Dave.

 

hope you get it sorted soon mate

 

I'll get to the bottom of it Lee.

Cheers Dave, i'll see if i can pop in tomorrow, depending on where my route takes me. If i can i'll give you a call in advance.

 

No probs matey, i'll be around all day

 

Didn't have any luck with the coil packs Dave, they were the wrong ones. When i went to remove mine i realised they had only one screw fitting where as the ones you lent me had two. I'll give you a bell regarding dropping them back up to you. It may have to be sunday as they've just fitted trackers to the lorry, so won't be able to do it in work time.

 

Have you thought about the fuel filter? It may be old and full of cack, fine when you not gunning it but it will have increased flow when you are.

Just a thought.

 

That's ok matey, don't get yourself into trouble
Dave.

 

Cheers Dave

Changed the fuel filter last year for a genuine Subaru one so shouldn't be that Ian. My bets are on a coil pack, but i've also got a spare MAF i can try swapping over.

 

From personal experience i've always found that even with an iffy coil pack if you changed the plugs it would run well for a while then the coil would damage it. Also. i've only found STi engines to have the coilpacks with just one bolt fitted, is yours an STi engine perhaps?
Dave.

 

The engine was rebuilt using a P1 block so i was told, so that may explain the difference Dave. The plugs i pulled out were in a brown colour which i've read is good. They'd only covered a few thousand miles so were pretty much like new. Someone else has PM'ed me offering a lend of a set so i'll try and get your coil packs back up to you on Sunday if thats ok, or i could do next saturday if thats better for you? Support like this is whats great about being in a club.

 

Next Sat is great but as i said no rush If you are comming then you could try a few bits off an import WRX i've just had in to ruls a few things out.
Dave.

 

Cheers dave, next sat it is then, top man.

 

Taylor,

I live just around the corner from Dave's place. I am down in Bridgend on the Saturday of Bank Holiday if you want to save a journey. Or does Dave mean 21st?

 

Next sat Ian, not 21st, that would be cool thanks, i'll PM you my address and phone number.

 

 

After borrowing a spare pair of coil packs from Scoobysim on here, i tried them today and hey presto, back in business. Going to be ordering a new one this week. So thanks to Scoobysim and to Dave @ ESP for lending a hand when i needed it, cheers fellas.

 

Do you still need the one's of Dave at ESP?

 

No their here in my garage Ian, they just need dropping off back to Dave.

 

I'll drop you a PM with my mobile number. I'll pick them up tonight as I am in the Pont

 

glad to hear all got sorted m8

 

Cheers Oz
Ordered a new coil pack from Import car Parts yesterday afternoon and it arrived at 09:30 this morning....can't beat those guys, service and price is awesome, had loads of bits from them and they never let you down.
