Good evening gentlemen,
For the past week or so my soarers been having some take off issues,
As I go to take off sometimes the revs will acctually drop too the point of stalling.

Did a service yesterday/today. Engine oils, gapped the plugs and did the transmission fluid also but now its worse than ever. About 50% of the time now the car will stall as soon as I put the throttle on from a stand still. The torque converter oil was not changed also. When the revs drop and it does pick up the gear after about 5 seconds it blows a massive fuel cloud and off I go. I have no problems as soon as its going aprt from a small misfire due too the freshly gapped plugs

Any ideas as too what this problem may be?

If it picks up 1st it takes off rather quickly, I've noticed it also has problems sparking while rolling sometimes, if I back off it won't spark propperly it seems, bit weird.
Unsure where the airflow meter is, its not on the intake pipe. Where is that elusive mofocker

now you will service your car every 10,000kms not every 70,000kms hahaha

1JZ non vvti doesnt have a AFM. they are MAP, as far as i know.

78K tristan ;D
Just checked the vac lines and map sensor. Both fine. Possible idea, set it on fire

correct, they dont run any type of afm stock. just map sensor & tps input

what gap you running?
im guessing less now than when you changed them?

maybe wants a bit more gap & could be too rich & bogging down??

running a piggyback etc?
probably get it on a dyno & check afr's, mines rich as fuck too so will soon be getting the safc tuned, probably at hypers

Plugs where at .26. Fail
Now gapped to .06
Changing that when ever I get the gap feeler of mr rad and going too .09 and seeing how it goes

.06mm?

try 0.9mm.
if you dont have feeler gauges, use a hacksaw. that will be about 0.7mm
