Mid_lifecry_sis Posted March 27, 2003 Share Posted March 27, 2003 TO REDUCE THE GAP IN MY SPARKS TO WHAT...? ok so reducing the gap will prevent the current problem near my max 1 bar which is causing the car to loose power momentarily, not fuel cut, more a drrrrrrrrrrr, noise and slight power loss only on heavy application of the accelerator. So - great advise from Dudersvr and others. What gap then ? Who's the clever techi that would know this !>? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted March 27, 2003 Share Posted March 27, 2003 Try 18 thou inch, less than that and the idle may go to pot or worse. The correct plugs at 25 thou should be OK though. I keep special race NGK ones in stock that I KNOW work up to 1.4 bar without a problem. Quote Link to comment Share on other sites More sharing options...
Willson Posted March 27, 2003 Share Posted March 27, 2003 No techi, but I did find this at........ http://www.mkiv.com/faq/faqtt.html 5. the engine misses at high boost. try re-gapping original plugs or new plugs at .026"-.035". start high and work your way down until it stops missing. I have gapped mine all the way down but I still miss when I really go for it. I'm pretty sure it's my coil packs though........... Quote Link to comment Share on other sites More sharing options...
Darren Posted March 27, 2003 Share Posted March 27, 2003 I think 30-35 thou for a BPU car was mentioned in the previous threads... Quote Link to comment Share on other sites More sharing options...
Willson Posted March 27, 2003 Share Posted March 27, 2003 Oh well, beaten by someone who knows what they're talking about ! It still may be of help, I guess............ 18 thou eh ? I'll have to try that little extra bit.......... the idle may go to pot or worse What is this worse that you speak of ? Quote Link to comment Share on other sites More sharing options...

That's the absolute minimum, the spark at 18 thou will be present, but may not initiate the burn, especially at idle, well enough. A crutch, for sure.

So - great advise from Dudersvr and others. What gap then ? Who's the clever techi that would know this !>? Mate I had exactly the same problem when I upped my boost. To fix it I bought and fitted 6 x NGK Laser Platinum spark plugs (PFR7B 4853) Problem went away and car goes like stink now without blowing rasberries under high throttle. :flame Dev I got mine from Chris Wilson above.

Willson Posted March 27, 2003 Share Posted March 27, 2003 I really don't know whether to spend 100 squid on some super plugs, or put the money towards my coil packs. I'm only running 1 bar so am I putting off the inevitable ? I guess the plugs have to be worth a go........ Quote Link to comment Share on other sites More sharing options...
Mid_lifecry_sis Posted March 27, 2003 Author Share Posted March 27, 2003 Good feedback cheers. I will try the plugs. Chris drop me a mail and let me know what the cost is. I'll also take a look at dropping to 18 thou pre purchase. Not being technical - both the expensive race and standard new'ish toyota are gonna be the same'ish in working hard at 1 bar - is this really all down to the gap or will the race plugs as stated make this all go away!? now I'm confused as to what makes the difference. Feel a mid'life commin on. PS: Screw new coil packs £! Quote Link to comment Share on other sites More sharing options...
