to motivate responses you might want to include some specifics... maybe what kinda car, symptoms other than "feels weak", anything that might help us help you... otherwise you'll just be helpless!!

Do you have a check engine light?

Stock ECU?

Did you do a tune-up before you dropped the engine?

If your feeling hesitation its probably sparl/ fweul related. What ECU are u runin? I was runin a PR3 for my GSR swap, old b16 injectors and a civic fuel line. The result was 45 miles to the gallon and some freakin BURNT spark plugs!! It ran fine for about a week and then started hesitating under slight throttle. My plugs are ruined. So... isent then ECU out to get custom chipped, got my fuel injectors rebuilt, they flow 250 cc's now all across, and bought a b series fuel line which is significantly bigger. Look at your plugs thats the first indicator. How many miles are you getin to the gallon? Are u using D series or B series fuel line?

hehehehe...what he said

buda18

there is no check engine light
and it should be the gsr ecu...ill check and see which one it is
i didnt do the install and when i got the car i didnt notice this problem so im sure they tuned it a little bit or whatever...but yeah im hearin alot that its spark/fuel related ill check all that stuff u said Mentat...also do u think it could the the coil or the ignitor?

nate_d

check out the fuel situation, if that is ok, then move on to the coil and ignitor, but in my opinion, its fuel related.
