Starting issues again (1 Viewer)

[Timid]

I originally had rpm fluctuations where the rpm’s would go from 1700- 600 rpm’s then die. I’ve cleaned the TB, MAF, no help. Thought maybe the fuel pump was going at 245k so replaced that along with the fuel filter. Still hasn’t helped. Originally when I scanned I got a p1120 code. TPS/APPS . Though in later scans I’m not getting any codes. Now on cold start engine revs up then 15 seconds later dies. Upon restart engine seems to be misfiring, dumping white smoke out of exhaust and the smell of gas at the same time. Never a check engine light/ never a limp mode. No apparent vacuum leaks either. Where should I look next? Thanks for the help. 98LX
