Need Help Extreme Hesitation!

[Tom95gt]

I don't know what happened I was just goin down the road and I felt my car start to shudder and I believe my CEL light came on but then it went off shortly after but continued to shutter so I let it sit and now it barely moves when under load... sounds like the left side of the car isn't firing but then it will go away slightly if i push in the clutch and rev it up. the CEL light still hasn't turned on again. I think that's all of the symptoms but please help. I checked everything underhood no loose wires or broken wires. O2 sensors, MAF?

Sounds like a tranny problem. You push in the clutch and it goes away slighlty. Sounds weird, is there any holes in your air intake between the filter and the plenum, there could be a leak and the maf sensor could be reading wrong. Idk just a thought

Pull codes and run a cylinder balance test.

Not a tranny problem I could here the misfire in the exhaust like it was running on 2 cylinders for a couple seconds

dizzie?

 

[Tom95gt]

The distributor is only a year old and its a good one so hopefully it shouldn't be that

I pulled codes
177 HEGO sensor indicates rich condition, cylinder bank no.2... Could be the long tubes but I'm replacing them now just in case
543 Fuel pump circuit open, battery to ECA... I have no idea what this means???

 

[Tom95gt]

Oh and I've been driving it today and it fell on its face pulling out of my driveway and once goin down the road and thats it so far... I don't get it

Sounds like an ignition problem to me. Might want to check under the cap and see if you have any corrosion. Could also be the PIP in the distributor failing.

 

[Tom95gt]

Update: Installed the O2 Sensors and so far so good... so no one knows what the 543 code is?

 

[Chythar]

Do you have some sort of an alarm or ignition cutoff that interrupts the fuel pump or the inertia switch in the trunk? If that's armed when you run the test that code will be thrown.

 

[Tom95gt]

Nope not that I know of
