so my sc300 with a 2jzgte swap was running fine untill yesterday.... to much went wrong at once.

My map sensor went out making it go from running glass smooth to what i described in the the title....

i replaced my map and spark plugs but its still running like crap and now the idle has gone from 850rpm to 2k. i dont have any boost leaks either. if anyone with a 2jzgte has any kind of help i would greatly appreciate it.

 

weird. no codes? battery / ecu hard reset do anything?

 

i did the ecu reset and didn't do anything. all boost lines are zip tied to there joints so no loose lines either. after i put the new map sensor in took it out for a test and it the motor went back to normal 1st thru 3rd gear pulls. but when i slowed it down is when it acted up again. so i figure i fouled the spark plugs which i did. put new ones in and help smooth some up the break up but it still breaks up. then my idle jumped 1k rpm to 2000... running really rich. i can get to about 3 grand with minor beak up and then its like someone pored led in the trunk and all torque goes away. i cant even get into positive boost it just get to 0psi and thats it. im a pt67hpqs so i know its not seals or anything. anyone here think its the crank pulley that broke?

 

are you throwin any codes?

 

um its an aristo 2jzgte so its obd1 and i havent done the pins yet since i have to borrow my friend's toyota diagnostic tool. regardless im taking my sc up to Top Speed for some proper diagnosis, but id rather fix something simple than pay for something that could be as simple as a bad ignitor. but if anyone has some advice on what it could be that woulf bw greatly appreciated.
