Re:LS/VTEC no low end power....help
 

well guess what guys, i fixed 90% of the problem, the Idle air control was bad (i changed that) AND i had a vacume leak on the intake manifold gasket (changed that too) then i changed the TB gasket, and the bottom end is alot better.

but i still feel a slight lag below 3500-4000, so an adjustable fuel pressure regulator is next to be installed.

the car idles GREAT, and it feels alot better.

I don't even have a throttle body gasket. I will get one tomarrow.

Re:LS/VTEC no low end power....help
 

Well I fixed the sticky throttle body but I still have a problem with my lower end. Plus when it warms up I have a bouncing idle. I might have some coolent lines mixed up or something. Anybody have any ideas?

Re:LS/VTEC no low end power....help
 

still have a vac leak somewhere.

Re:LS/VTEC no low end power....help
 

Yeah I fixed my bouncing idel by looking at the coolent lines. Right under the throttle body is where you can get into trouble. The coolent lines that come out of the intake maifold should go into the throttle body and some other ----. when it exits that part it should go into the therostat houseing. In some intake manifolds you will have a nippple left over. Just use a hose and clamp it on there and then block off that nipple.

untill you get a chance to add more fuel, It might help abit to set your timing at around 18-19 base. B16's run about 3-4degrees less timing than b18's.

Have access to a FPR? adding 4-5psi should get you close with the fuel.

Your plugs are a bit white huh?
