have not figured it out yet! i have changed fuel pump, fuel filter, checked tps (its all good), no vac leaks, no cracks in coil packs, gap on plugs (still black). still looking for answers on how and what to look for when testing map sensor! just keep trying and if you figure it out before...

how do i go about checking the voltage on the map sensor? been searching for awhile and cant find the info! thanks mkiiichip.

hahaha i just saw the hollywood! i got the throttle body off and im going to use the 2jz tsrm and see if its in spec.

did you figure out how to check the tps, if so how are you going to go about it. wish i still lived in L.A, we could just work on one car and speed this prosses of elimination up! i am going to remove the throttle body since thats the only way to get to the tps and use a volt meter on it. im...

check your o2 sensor per tsrm. or if you can borrow one try that.

put in the new fuel pump and filter and it did not fix the problem. i guess i will be taking off the throttle body to check the tps to see if its the culprit. its weird that both of are brand new plugs turn black. sounds like are issue's are the same to the tee. if its not the tps, i...

i have checked and adjusted the tps on a 7mgte but the information is inconsistanton for the 1jz when i google it. so untill im fur sure im not touching it. i am amlost done putting in the walbro and new fuel filter. and by 2pm Ill now if that was it...... i had the wideband on my 7mgte when the...

red arrow goes to the other side of the motor to iscv, the green arrow goes to the heater controll valvle that goes to the heater core. it will be on your firewall passanger side.

i have been looking all day and cant find anyt thing on the subject needing to removing it. do i leave it on the the throttle body and then adjust it if it needs it while its on there???? only thing i can find is using the tsrm for the 7mgte.....to check it, are they the same tps

http://www.youtube.com/watch?v=AYcm5rjdqgA I think this might be the reasone for it stalling out, i go very lean as soon as i give it gas, i should go rich as soon as i give it gas! i need to put in new fuel pump and new fuel filter i had saving for this kind of thing.

put in a new starter from driftmotion and it starts perfect now, no more slipping:) to get the top bolt off i went from the top of the engine and used a realy long handle socket wrench. installing had to use bolts on the back because there starter was not threaded, just used alittle gasket maker...

idle is at about 750 to 700. tps is getting adjusted right now. can the tps being off, make the spark plugs turn black with soot? they dont have any oil on them, its only unburnt fuel.

started the car for the first time yesterday and when i lifted my oil cap i found the milky oil on the under side. not sure if it is the same problem you had but it make me wonder. i guess the engine has been sitting for alot of years in japan and i just need to get the condensation out. how...

map sensor is there, its just behind the harness. jono, i will check that out, ive done it on the 7mgte. is it the kinda the same for the jz engine? i have never even been past 3k rpm's and when i took off my oil cap it had the milky crap already!!!!! is it just because the engine has been...

thanks sam, i just picked up some can's and im going to start prepping the rims for piant:)

no codes, and everthing looks good as far as plugs go, and all grounds are connected and tight. it kinda seems like it floods or it gets starved of fuel when i press the throttle fast, but the plpugs are black so i dout its lack of fuel.

checked all connectors, they seem fine. when i checked the spark plugs they were all black. cleaned them off and the made sure they were gapped good, but still want to stall out.

put a video of the first start

yes it does

just finished doing the 1jz swap and it idles so smooth!!! But as soon as i give it throttle it wants to die, if i go super slow and build up rpm's then give it more throttle its fine. i can put up a video but its kinda hard to tell. what could be causing this issue, i checked, coil packs...
