I regapped the back three plugs runs a little bit better but still the same symptoms mostly

Sooooo you regapped those Junk plugs, lol

ya didnt see the thread till last night :/

reset the computer, now my boost gauge is more accurate than it was when it wants to work, engine runs fine at low speeds, when im in forth gear on the freeway the engine is really knocking real bad, 1-2-3 gears still wants to really struggle to gain power after 3,000 rpms, when let it idle, my lights get kinda dim at night especially when the fan kicks on, the lights brighten up when i gain some speed, it seems to want to run a little better after i unhooked my 4,000 watt stereo going to try a different coil pack I have new Bosch wireset might also put some ac delco plugs in cause there are bosch goldplus in my car  plugs damn 1 autozones recommend previous owner replaced the alternator

car alarm started going crazy, locking unlocking my doors, cleaned up the ground for the power antenna, cars seems to runs a lil better knock on wood

Installed that check valve on the vac modulator today, also found that maybe one of my spark plug wires came loose from one of the coils, but it was caked with die electric grease , runs perfect now on top end, shifts better than it ever has 5,500 rpms, engine still wobbles when i ease on the throttle in 4th gear thinking this must just be my upper motor mounts goin bad again :icon_rolleyes:

You mean it seems like it shudders? in 4th gear that would probably mean your in (or tying to go into) torque converter lock up, wich when the converters going bad, it shudders when trying to lock up. Dr. Tranny has a little packet of stuff called shudder fix thats suppose to work really well for that.

I swapped my top braces for the upper motor mounts, seems to not shudder while at WOT,  it does shudder when I go into forth gear slowly, if i go into it faster seems to be ok, is that stuff safe to put in our old cars? I had my tranny flushed at 100,000, odo is 138,000 now, do i wait awhile then put that stuff in before a flush?

Have a new acdelco coil pack that needs to be installed as well as a tube of doctor tranny instant shudder fixx

does any one have a pic of where the cruise control cable is please?

ok symptoms are coming back a little bit, the spark seems to break up at high rpms again, not nearly as bad as before, especially when im in forth gear just ideling down the freeway, seems to get worse the lower the tank is on gas, I reused the old fuel pump pulsator when i replaced my fuel pump and used the new larger O-ring for the fuel tank lid that came with the pump, seems to hold presssure ok whenever i go to fill it up pressure does release only after running it for while, I have one new coil pack that im going to try and doctor tranny instant shudder fix

If your coils are good, your plugs and wires are good also, then check your Ignition Control Module (ICM).

replaced all six plugs with acdelco .45 gap and it doesnt run on the freeway again,  I unhooked my stereo, and if I ease on the throttle it will take off, If I put it to the floor seems to flood imediately, would a low battery cause this as well? My battery dies ike twice a year when im running my 4,000 watt audiobahn set up

Possibly, have you done the "Big 3 wiring" upgrade.  Sounds like you aren't getting enough voltage to your ecm and sensors.

prolly going to gap the plugs to .30, then try to figure out how to change these coils packs, if all else fail ICM, maybe a low battery would cause this as it dies about twice a year
