Please Help
I just bought a 93 Formula 6-speed, it runs a really good up to 3000 rpm then it starts sputtering and has no power, any ideas?
thanks in advance

Put a fuel pressure gauge on it and see what the pressure is. Inspect spark plugs and wires, inspect or replace ignition coil and ICM, inspect or replace fuel filter(could be clogged or all gummed up)
Pull the valve covers off, inspect for broken springs, rockers or anything un usual.
Could be a lot of different things. You just have to start with the basics and go from there with trouble shooting. There isn't going to be an exact answer anyone can give.

Does the SES light come on? Even if it doesn't, scan if for codes, there are codes that don't turn on the SES light. Very easy to read codes on a 93 using a paperclip.
