So it starts it runs, i tried driving it today...put it in D and nope didnt go anywhere....woops forgot to put in tranny fluid!

. So i fix that and take it to the street, went down an incline with my new brakes (w/o bleeding them cuz i was anxious

). and started on my way around the block, only on the way up to the first stop sign its all an incline, flooring it i think i hit ABOUT 1900 RPM and about 3 mph

. Sigh, i get pissed and go back to my drivway at dangerous speeds of about 1-2mph, i get to my driveway and stop, not cuz iim on the brakes but because i have no torque at 1500 rpm and flooring it, after 30 seconds of flooring i finally get up to the top. IM still pissed then it occurs to me 30 minutes later to check the throttle cable, i revved it by hand and VRRROOOM it went which tells me i need to seriously tighten that wire. My question is just for quick reference when i do this tommorow, besides tightening it under the hood, if for sum reason that doesnt work or its tightened as far as it can go already, is ther a way to tighten it near the gas pedal??? ive never really looked under ther.
**another question:: i have a 88 7mgte supra, we through a rod bearing we believe (since the rods were sumwut recently replaced) so its knocking bad. The bearing is very simple to replace, but since the knocking, would that do a bad number on the crank????? enough so to replae it? keeping in mind almost immediately when it started we turned it off and only turned it on a couple times after that for diagnosis reasons. I have an extra 7mgte block and all accessories, including crank, if necessary, is it possible to replace that W/O taking out the engine or no? ive never cracked open a 7mgte, maybe sumone here has or has the know how
