Hi. Just got a 88 n/a 5 speed having a issue running after it warms up it runs like crap missing and sputtering with no power. When this first started it was intermittent, and was a warm starting problem. Changed fuel filter. Then began starting and running out of gas after the pump primed. Pump has to be re-primed to start again. Pump seems to be working fine. Ran a code 22 and 23. Fuel pump circuit, and idle switch circuit. Any ideas. Fuel pump relay possibly? What about the idle switch circuit , does this usually come on for any certain reason/part/sensor? Or is it most likely grounded out/or bad ground? I know there's a bunch I left out, and I appologize. This is like the fourth time I've wrote this on my little phones keyboard. Just reply n ill elaborate. Thanks!
