Folks we need your help on a 93 LS400 with @ 140K miles. The engine would stall after running for about 2-5 minutes with black smokes as it dies. It would start and run again immediately, but problem repeats. We think it is the cold start injector, but not too sure.

Please help!

Thank you so much in advance!

Best regards,

Federal98

 

its probably your maf sensor, goto lextreme.com and the v8 forums you can find maf schematics with the information to check it with a volt meter and you might want to adjust your tps
