I have a 95 eclipse my fuel pressure is at about 42, but when i rev it up it goes down, by about 5-9, then it comes back up,is this normal?I also have a problem with it dieing sporadically and have a general loss of "pep", is my fuel pump bad? my fpr,btw, is brand new. TIA for any and ALL help!!!

Check vaccum hoses for a leak. I don't think it should dip lik ethat before it rises.

Thats just the thing its not rising at all its just goes down when the RPM's go up, and now i am stumped here's what i have done-

replaced fuel filter
" spark plugs (all gapped at correctly, i checked 3 times)
" spark plug wires
" front o2 sensor
" new computer less than 1,000 miles ago
" replaced cat with a test pipe
" ignition coil
" Fuel pressure regulator
Just as a side note all the vacuum hoses are silicone and are hooked up (i doubled checked) no wires are melted or shorting out(i checked twice) I am not getting any CEL, and no fuel line is pinched or ruptured, and as you can see it's starting to get expensive, i am stumped!!!

BUMP

how many miles are on the car? It could be the fuel pump but check w/ an ohm meter while running the rpms up. you may have a drop in power under load. If that is it replace the ground wire with a thicker gauge wire. If this doesnt help I really still cant tell you its the pump, but your really running out of things to change so you can bite the bullit and change that too:thumbsup what the hell its just money right.....right:-)

you talk about new ground wire. Which one are your reffering to ? from where to where?
