94 z28 that when i step on the gas it takes 3 sec to get to 2.5k than it puts me back in the seat

How are you killing mustangs if you have a 3 Second Delay?.
Also it could be too many things to just target one. I would check ignition and fuel system. If I had to take a stab in the dark I would say it was a bad ICM or coil

[mustange kiler]

wel after 2.5k its normal when i also steping on the gas it knocks

[FormulaLT1]

When was your fuel filter changed last?

[mustange kiler]

it was cjange a week ago and when i let off the gas the tack drops down to 1k

[FormulaLT1]

Do you own a fuel pressure guage?

[mustange kiler]

nope

[FormulaLT1]

Well think about buying one. So you can start testing stuff and eliminating possible cause's

any check engine light???

opti?

[FormulaLT1]

When opti's start to go they tend to start at higher RPM's and then get worse. but with someone not having the correct tools or basic understanding of engine operations there is no way to find the cause without him bringing his car to a mechanic

i talked to some hut and they said it might be my fuel injectores

[FormulaLT1]

It could be your injectors, the problem is it could be almost anything in your fuel or ignition systems. The best bet unless your going to invest in the tools required to test for possibles causes is to take your car to a mechanic. it will save you headaches in the long run

seen optis go out on the lower and higher rpms. higher rpms are the normal, but the lower happens as well but it is rare. Usually when it happens, people Nickle and dime themselves trying to figure it out by overlooking the opti.
