Question about Cars & Trucks
I'm thinking you took it to a point and guess shop.? I think it is this, Nope, Now I think it is this, nope......Well I'm thinking it is a bad fuel module, because of where they locate them. Could just be the plug, corrosion. I'm also thinking you have a bad ground also. I'm also thinking you should find another shop, And demand your money back for a misdiagnosed job, that didn't fix the problem.

do you have any check engine lights on? If you do, that is the first thing I would have checked. It does sound like plugged EGR, vacuum leak, or bad TPS

I had same problem in my 90 deville. Drove myself crazy, I replaced the sending unit in the tank with a new fuel pump. I also had to replace the fuel pressure regulator, which sits behind the rail system. It worked for me.

The error P1130 and P1131 is for the fuel trim and lean fuel mixture respectively. This tells me that this may be an issue with the air fuel mixture or its reached its limits in compensating for the incorrect mixture. You could try to clean out the intake first using carb cleaner spray or tuner spray to clean out the intake and the MAF sensor which measures the air that comes in. Check also if there are leaks or gaps on the air duct found between the air filter and the intake manifold and the intake plenum. Leaks would cause the system to get an incorrect reading. If it were a faulty sensor you should get the error code for the sensor and you may have issues starting the engine up.
Check also the vacuum hoses which may be loose or cracked that needs replacing or refitting. This is also a common cause. I also do not rule out the possibility of the fuel sensors going or starting to go bad. The PCV may also need cleaning or replacing.
With all mentioned items go check first the leaks of the intake system and the vacuum lines as these are found to be common. Some leaks or cracks are minimal but is crucial to the sensors.
