I’ve been working on a 95 Lesabre for the past few months. Car has 51k mile on it. Starts and runs pretty good, but idles rough sometimes, stall sometimes and had hard misses between 30 and 35 sometimes. Terrible gass mileage. Replaced the crank shaft sensor, resplaced coil packs, plugs and wires. replaced the upper and lower intake manifolds. replaced termostat, collant temp sensor. Still had low fuel pressue, so resplaced injectors, fuel pressure regulator, fuel filter and fuel pump. Has same low fuel pressure as before repairs. 38 PSI at rest and 32 PSI with engine running. I’ve looked for vacuum leaks and replaced all vaccum lines. Want to address the fuel pressure issue before moving on to other issues. I’ve cheked the fuel lines, connecters, etc. Don’t see anything that looks like a problem. Any thoughts or ideas of what I should look at next would be appreciated.
