well, my car is offically GHEY (actually, now its not any more!!!)

ive had it with my bloody car, ever since i bought it it has had issues (ie it will NOT rev past 4600rpm NO MATTER WHAT, and then missfires for 20 secs after i change into the next gear) i was sent to this site by someone on caraudioaustralia.com, in the hopes someone here could help me, but to no avail.

my first thread was on this exact topic, i would post a link but i cant be bothered searching for it.

today i reached the end of my teather.

i have replaced the air filter, fuel filter, leads, spark plugs, rotor, cap, valvesprings, put in a vernier gear, checked timing a billion times extractors and exhaust with new cat, put in two different computers borrowed from friends, even tried a chiptorque chip down at BWCP on a E-series cruise that was borrowed from lukey039s brother, pulled the injectors out and sonicly cleaned them and fitted new strainers, checked fuel pressure at least 14 thousand times, swapped the XR reg for a stock one...the list goes on.

so today i replaced the last possible thing that could possibly have anything wrong with it: the coil.

and it made SFA difference. the sh!tter still wont rev out and its KILLING my quarter mile times, not to mention the traffic light grand prix's that i never engage in....AAAARRRRRGGGGGHHHHH!!!!!!!!!! IM GUNNA BURN THE F*KKER!!!!!!!! my mate has a bog stock auto EB MPFi 6 that revs hardcore right to the 5500rpm cutout - WHY DOESNT MINE??!?!?!??!?!!??

this new engine/computer combo cant come fast enough!!!

yeah fuel pump is fine, have swapped 02 sensor as well.

forgot to mention that i have also swapped the MAP sensor, and bought new air temp and water temp sensors too, all to no avail.

quickcorty - it doesnt 'bounce' like when you hit the limiter (it will hit the limiter in neutral, but under load no go at all) it just goes up there and stays at 4600, making little missfire sounds occasionally.

its healthy until that point (it makes [email protected]) but it wont rev past it...GRRR!!!

I know you have replaced the HT leads but it wouldn't be the 1st time a new set were faulty. Anyhow just check under the bonnet in the pitch dark somewhere with the engine running and see if there are any stray sparks on the HT lead, the coil or TFI.

I'm really sorry to hear about your frustration rollin. As you know, I'm very familiar with the urge to burn a blasted car that just keeps annoying you! Interesting that it revs fine in neutral... it's not something bizarre like the transmission or your new diff or something strange is it :eyebrow: in which case you're going to be even more annoyed when the new engine / computer combo is installed :fraz: Can you cruise along and then select a lower gear and carefully try to bring the revs up past 4600 to see how she behaves?

Distributer worn out, have you checked the timing at high revs.

With all your frustration go put it on a DYNO - i am sure you will solve it then.

All that money you would of been better to buy an ef engine. New engine gearbox and diff and you should be out of problems. Maybe your computer ?? Long shot but i had a computer in mine it was fine but when i reved up high was shaky as a bitch. Anyway i replaced it all problems fixed. I got a problem i cant seem to get damn traction anymore with this manual :/

rollin, I don't want to scare you, but what about wiring looms? Is there anything that looks crappy?

EDIT: Not having a go at you, I'm sure you've checked all this out a thousand times, but maybe I'll stumble upon something you haven't checked if I keep rambling enough :dj:

Rollin. The last time I took my car down th track at Calder I had a revving issue as well. Was fine till 4500, then after that, just died in the ass, like I was out of fuel. I had to cross the line in 5th with a 14.9. Funny enough, it ended up being that the engine was slightly low on oil.

I had just under 5L in the thing at the time (probably about 4.75), now I put about 5.5L in and have not had a problem since, and 5500 is no problem, even with the swirl in the chamber.

Just thought i'd share that.
