Hey everyone, Krispy here. Jenny is having some issues lately and we're stumped. I'm not finding a whole lot of similar experiences through the forums so I figured I'd create a new post. A few days ago, I started to feel a lag in the truck. I tried to get on the interstate to go to work and couldn't get any power(torque not electrical) at the beginning of each shift, or anything above 60 mph without the truck feeling like it has someone tugging me backwards. When shifting, it'll hold onto a gear for a long time and then finally kick into the next gear rather hard and go. It's been gradual, and I've had to limp the truck back and forth to work. Yesterday I left for work but as I stepped on the gas pedal barely anything happened. The engine sounds like it's doing what it needs but isn't getting a signal to send torque. I already had someone check it at the transmission shop. He thought it was fine and believes it's either bad cats or a fuel issue. We've checked into the fuel with a pressure kit from OReillys but it didn't fit quite right so who knows if the test really worked. Then we found a couple of cracks in the exhaust manifold (the noise from the manifold had gotten worse as this started) so we took that to the muffler shop and had a whole new passenger side exhaust manifold replaced but still no solution to the power loss. Also a plug that we made for the ait intake resonator delete has melted and was letting in more air past the MAF sensor. So we're guessing that between the reading of the MAF and the O2 sensor on the manifold, the fuel ratio was all sorts of messed up. Again, this has been gradual with yesterday being the day I couldn't get the truck to push itself through an intersection on a yellow light (I was turning left). We're thinking about changing out the distributor (the whole she-bang) since the cap and rotor have already been changed a while back and aren't likely the issue. I'm just not familiar with what could go bad all of a sudden and so gradually. Please help!
