Hey guys,

My mate has just got his r32 4 door anyways he needed new coilpacks as the original ones were stuffed so he dropped in some new splitfire ones and car is still playing up.

Its not making any mis-fire noises at all so that would say that the fuel pump, coilpacks and sparkplugs should be fine.

But its shuttering the whole time u drive it even when its not under full load...u can feel it like something is holding back....when under full load the car is accelerating so slow....when i put my foot half down on throttle thats as fast as his is on full throttle.

Im thinking it could be the timing....what else could it be?

Hey Luke,

Try to clean out your air flow meter dats all i can think of without having to go spending big bucks.

Try replacing your throttle position sensor. 110 delivered to Eastern states from Justjap. Sounds like what I had. I had weird shuddering while driving, (at least, that's what I think your describing). I also had slightly unsteady idle. When driving full stick, I couldn't really tell anything, but if I slowly wind out 2nd gear, I can feel it sort of hesitating now and then like it's gotta think about what it's doing. I also replaced the oxygen sensor as a first guess in the hope of fixing it. My mechanic garantees it's stuffed, cos he adjusted it and it idled perfectly for 15 minutes, then he drove it and straight away it was rooted again. He swept everything with an oscilloscope and got no faulty readings, but said when he lightly tapped the TPS with a hammer, it went absolutely berko and misfired as I was experiencing. Give it a go! Can't wait til mine's replaced (day after tomorrow).

Its a long shot but worth a try...my old car had the same problem and i spent a fortune trying to rectify the fault...did all the usual stuff like fuel and ignition but to no avail...finally found the problem to be a some frayed wires going into the ecu...have a look...it might just be that...

    • My take on gg2 48mm, 54mm, 58mm, and 62mm compressor map for same size compressor vs gg1 : All gg2 only outflow gg1 above 20 psi. As all g gen 2 surge line at lower left of comp map move to the right, all gg2 sacrifice spool vs same size gg1, surge line move to the right worst for 54mm gg2. So for same size compressor if you want best response, use gg1, if you want max hp at >20psi use gg2 but you will be laggier vs same size gg1. Max compressor efficiency drops to max 75% on all gg2 vs max 76%-80% of same size gg1. Iirc lower efficiency means hotter iat less dense air so lower hp at same operating point of comp map. Also curious why gg2 is mapped to lower max rpm vs same size gg1 (only 48mm size both gg1 gg2 mapped to same rpm) : 54mm gg1 165,000 rpm  vs  gg2 160,000 rpm. 58mm gg1 150,000 rpm vs gg2 140,000rpm. 62mm gg1 145,000 rpm vs gg2 140,000 rpm. If gg2 can safely spin to gg1 rpm then they can flow a bit more than as mapped. Good thing that all gg 2 interchange compressor and turbine housings with same size gg 1. So gg1 owners can buy gg2 chra only if planning to boost >20psi.
    • My stuff is all with Shannon's, granted, I don't really have imports I'm driving on the road, however, I've had multiple cars at the same time with them. Presently we have the Landcruiser on laid up cover, Sarah's Kluger on full cover, and the house insured. About 18 months ago Sarah wrote her Subaru Liberty GTB off, insured with Shannon's, and the payout, and buy back of the wreck was super quick. In 2020 we had the VF Commodore totalled in a major hailstorm. Storm was on the Saturday, I called on the Sunday and lodged it, vehicle was towed on Tuesday night, assessment team called on Wednesday to say it was a total loss and get payout details, money was in the bank on Thursday morning. Have had a few other claims both at fault, and not at fault, over the years, and never had an issue with them.   Funnily enough, they're also the cheapest insurer I find for things like Sarah's Kluger.   I will say I'm less impressed dealing with them lately around "the experience", as a lot of their staff that you deal with aren't car enthusiasts. Shannon's has a much more main stream feel ever since they decided to become "big corporate", laid a heap of staff off, and then hired a bunch of non enthusiasts. At the same time they've been making a push to be less "call us and we'll personally have someone who cares help" to "hey, this computer can do stuff for you" and are trying to get more square pegs to fit round holes. (That's just the vibe I get from them). Again, have had no issues with claims with them, but get a bit of a "less personal" feel from them.
    • A thing I wasn’t happy with with enthusiast was during the initial phone call they told me they’d insure it for 130k but needed photos.   I then sent them photos and they told me $80k as there were other cars either similar modifications available for around that price, I told them to send me the links to said cars so that I can buy them. i then sent the modification list with prices of the parts (no labor) and the price then came to 115k, which is still shy of the 130 that was agreed in the initial phone call 
    • Ask me a bit later this week before payday
    • I agree that delayed payment probably isn't the most suitable solution. It seems a solid complete transaction would be best. As I wouldn't be using this sale as a line of credit that would typically earn interest, we can probably arrange a much cleaner single transaction deal. I can do $92.52 today. Would you prefer EFT, or Cash on Pickup?  😛
