Looking for some advice.
My car did this last week after getting fuel (98)/ It woulnt rev past 2000rpm no matter if you selected any gear/neautral.I Suspected fuel but now I am not sure as its spot on 2000rpm and when you hit that limit it drops down to say 1000rpm and goes back up.
Anyway I went to show my next door neighbour whos a mechanic after it had been sitting for a while (maybe 1/2 hour) as he suspected an air leak but it ran fine a didnt do it at all.
Now that was a week ago and its been fine since then but low & behold it started today.. It started fine and i drove done the shops 10 mins so the car wasnt evenn warm. Stoped in that shop for 15mins & started again for 5 mins in another shop and when I got in again then it started just checked the temp and it got to 68 degrees so not even fully warm
I have cleaned the AFM & connector with contact cleaner as I suspect something along this line but I am by no mean mechanically minded.I am not sure what should happen even if you unplug the AFM while running?
Now the car has the following mods...
Nistune Z32 ECU
Solid turbo inlet piping (made by Scotty) to air box (hopefully see him tonight to resolder AFM plug wires??)
Yellow Jacket coils
Throw some ideas at me please?
Ps:attached a short video of whats happening when just revving the car in neautral
Just had the above 2 tests performed on my car so i thought i would post up the results online to get some sort of feedback..
Compression Leakdown %
CYL1 135 PSI -- 15%
CYL2 145 PSI -- 11%
CYL3 135 PSI -- 27%
CYL4 135 PSI -- 24%
CYL5 140 PSI -- 16%
CYL6 140 PSI -- 13%
Cylinder 3 & 4 had higher % leakage indicating? valves etc
The reason for these tests are that i am blowing a bit of smoke under WOT (using oil) so I am trying to eliminate certian things. My Turbo is an SS1PU Hypergear so is less than 6 months old so maybe oils seals who knows.
Please provide any feedback you can...
