No Grunt

[NIZLAH]

hmm that is quite strange....
Do you like the note of it?

------------ > Yeah my mate and I believe its a tvis issue.. just haven't been fucked enough to play around with it yet.

[70XIN]

a completely open/completely closed TVIS would still make the car "go alright" below 4000rpm, i really dont think it's that .. worth a try though i guess

[NIZLAH]

yeah that's what I was saying to old mate... its really strange though, as soon as it gets to that tvis range it opens up sweet and pulls strongly...below though it just has no response or power.

Thats exactly how mine feels, ya, the exhaust sounds the job.

The car had a shit attack this evening in indooroopilly, all of a sudden it developed a massive miss, sounded like a rally car with anti-lag, pulled over while I was now having a shit attack thinking the head gasget was after failing. checked as much as I could with no tools, did notice a split in one of the leads. Started her up again & drove her home without her missing once.
Bizarre,,,,,, New leads & a dizzy cap in the morning me thinks.
Then when I get the exhaust sorted Ill bring her for an expert opinion.

my 4age is doing a similar thing. below 4k its almost like its missing or running on 3 cylinders but once it gets past 4k (roughly) it just takes off like a rocket. mine does have some big cams but last week it wasnt doing this so the cams arent to blame.

i did have a problem a few weeks ago where the TPS wasnt working properly and the car just died in traffic, luckily i spotted the loose wire and managed to tape it in place in the middle of peak hour traffic and she was fine after that. im pretty sure the problems arent related but that could be something else for you to check.

im going to investigate thoroughly this weekend so ill let you know if i find the problem.

I have done the below & still no good.
New plugs,
New Leads,
New Dizzy Cap,
Swapped Map sensor
Swapped temp sensor @ rear on head
Swapped ECU
De-Cat pipe incase the cat had collapsed
Compression test very good
Fuel Pressure very good
Had timing checked professionally as the belt is >5000km old, bottom marker, top dead centre etc,etc all spot on.
Checked T-Vis & replaced actuator

I think thats about it,, once again t
Car smells a little rich but that could just be the new exhaust as I got the wrong gasget & didnt have any cement so it is blowing a touch in the middle. The symptoms again, no grunt/power esspecially low down. No toque, wont complete a dounut from 6000rpm without clutch kicks

What's the ignition timing set to (not cam timing)? It sounds like when I retard my timing to 5deg, has no torque down low but as soon as 4-4.5krpm comes along it revs well.

Setting timing to 15-20deg advanced without TE1 and E1 connectors bridged should give it loads more low down

[marvis]

Maybe I should come over and I can try yelling at it?

[Killswitch]

Bump.

Anyone have any more ideas about this? My car is doing something very similar (Bigport ADM ECU) 4500~ rpm you can feel a kick and it actually starts moving. Below that its fucken slowwwww. Also is using a fuckton of petrol. TVIS is definetly working as when disconected it runs even worse in the lower revs.

Similar to Eircamae86 the motor seems healthy enough! comp test/fuel/ignition and timing etc. No error codes...

Annoying!

Cheers
