sounds like a lot of are 240s are bogging (why)?

I had a 89 240sx sohc ran assome! the timing chane broke so i bought a nother one but a fast back. It needed a fule injector so i put that in and i just can not get it to run right. If i give it 10% gas it runs ok any more then that it will fall right on its face. Timing? vac not hooked up? I just can not figure it out.

start by checking basic things, MAF, ECU for codes, make sure all your injectors are firing properly, etc...

a quick search should bring any of those up
