Re: How to check for a faulty FPR (Fuel Pressure Regulator) and replace it

I still get horrible MPG, I suspect it the injector.
Is it advisable to use carb cleaner in the intake manifold. Also while I'm here, if I get a 95 intake Manifold would that increase my hp up to 300? Would it be possible.
Also how do I test the FI.
Also to correct my previous post: The dealer discontinue the 4 bolts that hold the intake, But the 10 pieces of T30 with rubber are not. They are sold as kit only. They run about $70 for all 10 bolts with rubber while I need only 2 bolts w no rubber. The previous owner use a stainless steel and it was pain in the arse to remove it.
I didnt get to look for the drain plug for the radiator yet can you also point it out?
