Hi guys,

I am having issues at high revs 4-5grand +, with my car spluttering and poping and losing power. We dont think its the timing or the knock sensors after running a diagnostic computer.

A few people have said it could be the coil packs, how do i check the them? It would cost a lot to replace them and if there isnt a problem with them that could be a real waste of money.

also another person mentioned the air flow meter.. sound like it could be the problem?

*tear*

cheers :rofl:

  • 4 weeks later...

i had the same problem mate my coils were fine

however it only started happening when i put in new iridium plugs. for the moment i gapped them right down to .6 and this fixed the problem but still happens from time to time

i am going to put some copper ngk plugs in next i have a feeling its the iridium plugs but i will test and see if its is

How do you know your coil packs are fine?

i took them out and thoroughly inspected them no scorch marks cracks etc plus the fact that they work most of the time now makes me think they are fine. coils are either broken or working from my understanding they dont work intermitently??

also my car was fine before i put iridium plugs in it then it started happening

    • So.... the K&N air box thingo was too big, ended up gifting it to a mate, well, by gifting it he actually supplied food and beer at the pub,  which was nice, as it will not sit on a shelf in the garage for the next 10 years I did trim up some of the existing stuff to neaten it all up and gave it some wrinkle paint, unfortunately it currently has a used and abused mish mash of different types of hose clamps, 4 big fat T bolt type (shit), and a few normal clamps of vairing sizes and brands, but..... only until the 6 constant tension black worm clamps that I ordered from EFI solutions turn up next week Currently the current hose clamps are triggering me hard, LOL Is this the final version, probably not, I really want just 2 silicone pieces, a straight bit of silicone from the filter to the MAF is easy and will happen as soon as I head into Just Jap tomorrow, the problematic part is a 30° silicone bend from the MAF to the TB that I can connect the engine breather from the head, I found that there are bulk head fittings for boat bilge pumps that should work, but until I can get a 30° silicone bend the alloy pipe, and the 11ty thousand hose clamps, are there for the foreseeable future 4 hose clamps are golden, 6 are grudgingly acceptable, the 8 currently holding it all together is just taking the piss    I've also ordered 60 more retaining wall blocks for the front yard, I mis-gonculated the height that was required to get above the base of the Photinia's (red robin's) that are the hedge behind the front fence, currently it is 2 blocks high, and about 1/2 a block short, so going 3 blocks high will be above the base of the red robin's, and allow some room for mulch
    • It is the stock air box with the panel filter. Everything else is stock except the exhaust at this point, as I also went back to the cleaned 270cc injectors. I will check the RPM when the IACV is unplugged and report back.
    • As MBS suggested if this is happening when the engine is cold you're going to want to remove the intake air regulator and verify resistance + that the shutter is physically opening and closing. At -20C should be fully open, 20C half open, over 60C fully closed. At 20C should be 70-80 ohms. For AAC valve testing using a Consult cable see if you can raise and lower the idle by commanding more or less AAC duty cycle. Hopefully it's pretty linear as well, shouldn't be like 30% AAC valve is barely idling and 40% is 1500 rpm.
    • Bloody apprentices! 🙄
    • Not sure yet.  Was considering speedtek because it was rated to 800hp, but when I did some research about him I don't think I will go for that🤣 So maybe giken gear set, but I'm afraid it won't be strong enough🙄
