Oh it was cutting out and wouldn't start till I changed the tps and throttle air bypass valve but still got low rpm and sluggish driving..

sufficient fuel pressure? by 'cutting out' do you mean the fuel pump stopped working....then began working again? or the intake is so clobbered up with carbon from a defective EGR that it has trouble even running?

Plugged Cat? Check Engine light on? Bad gas?, Overheated Transmission? fuel pump? Loose nut behind the wheel? What else is going on with it. Every little detail helps.

the fuel pressure regulator has black butyl rubber hoses which are cheap and crack....replace them with silicone vacuum hoses (though more expensive) will last and last and will NOT leak...you see if there is not enough vacuum to the pressure regulator it will not produce ANY fuel pressure and be weak....and the leaking vacuum hose will make you run faster...with no uuumph...because the air/fuel ratio has been upset now....just another keen horror tip of lack of performance from your ole' pal judge_roy~
