Yuck... I'm sorry but you bought a boat, ("b"ail, "o"ut, " a"nother, "t"thousand) there is quite a bit it could be... It could be anything from coil rails to timing sensors,... I know its not the same make or modle but u had to replace the distributor " or equivalent of on a 99 camaro ls1. After I went through "ASE" certified techs they were still stumped... I'd go get your money back under lemon law... If u can... It's a dead weight unless u want to invest thousands


I would look the crankcase sensor, the catalytic converter also look to see what the fuel pressure is at the rails..


check the TPS The position sensor, or the idle position cylinoid I believe it is? Yeah it sounds like the guy stuck you with a bad car I'm sorry.


Throttle position sensor
