ok so since ive started driving my camino after sitting in the garage for a few years im fixing all the little issues i can find. So far ive replace every noticeable vacuum hose, removed the heat riser hose and plugged off that vacuum hose opening adn closing the heat riser.
i just put 6 copper plugs in (4.3L V6) gapped them and everything. car is deffinitley running a lot better then it used to. Wires and distributer and cap look fine.
my problem is i seem to lack throttle response if i matt the throttle at 700-1000 RPM the car will choke out and sometimes stall. I have electronic TB injection and have eliminated every electrical problem from the throttle body. im guessing i have a fuel filter of fuel pump thats clogged or not pumping.
my question is in an 86 elco is that fuel filter and pump in the tank? i looked underneath without a lift or jack and couldnt find any filter outside of the tank. am i missing something here?
im 90% convinced i have a fuel delivery issue but cant find where its not delivering from....
i ordered an OBD1 to USB cable to hopefully diagnose what my pressure is in the fuel rail since i have all the software already.
but putting the diagnostics port aside, what do you think? am i right about fuel delivery?
when i replaced the plugs they looked almost perfect other then i can tell the motor has been run hot a few times. ran a tad lean but nothing serious. im just confused at to whats causing this other then fuel delivery.
im trying to avoid dropping the gas tank and tering into filters/pumps inside if theres an easier way to diagnose or fix..... HELP!
