Whats wrong with my baby? (94z28lt1)
When i get drive it, it either gets hot and stops to get sluggish, aka feels like shit when i accelerate, and on the freeway after 50mph it starts to get sluggish and gain speed slow as hell. sound like it's fluttering

could be the opti, when was the last time it had a tune up(plugs,wires,fuel filter) ?

I'm getting plugs/wires and fuel filter change next weekend

p.s If i do replace opti, is jegs good enough? or should i just get MSD? I am putting all performance parts in everytime i replace something (i.e NGK plugs, MSD Wires Headers/cam/heads soon as i can start saving when my ride is riding like it should) anyone?
I plan on stopping at heads/headers/cam. then just doing better gears and rear end and new trans .

anyone? trying to see what to check while i do everything.

cause soon as it hits 50mph it starts to make a sound like if someone was opening and closing blinds real fast.
I still goes up in mph but like 1mph every few seconds...

you said ur getting the plugs and wires changed next week... as in youre not doing it yourself? A shop will charge a rediculous amount to do the plugs and wires

and the way you describe that sound, it does not sound like an opti it sounds more like an internal problem

come to thinka it, do you still have a cat(s)? could be clogged..

I had my cat go out a couple years ago and there was no place for the exhaust to vent, the car would start overheating and had NO power

Duplicate the problem and then pull the wires off one by one and put an extra plug you have laying around on them to make sure that its a spark issue before you go throwing parts at it.

If you do have to replace the opti, the MSD unit is supposed to be pretty good, but a few have had problems. Could always be operator error, however. I would get the MSD or a new AC Delco unit. You can find the Delco units on Ebay from thepartsladi (I think that's the name) for a reasonable price. The Delco units will support alot more power than people give them credit for.

Oh, and I wouldn't just get a cap and rotor, get the whole assembly.

Yes im getting them changed, unless someone can link me to a site so i can start trying to do things myself. Im changing wires/plugs cause i think one of the plugs are burnt, and i know forsure the wires need change
