1994 Dodge Ram • 135,000 miles

My name is Bob and I have a 1994 Dodge Ram 1500 4x4 5.2L Pickup. I noticed a slight chirping noise. The truck ran fine good get up and go. I tuned it up because it was time. I changed the plugs, cap and rotor. After which I had gradual pick up but not able to punch it and go. It bogs and when I let up on the gas pedal it starts to pick up again. Mean while I get this slow chirping to fast and back to slow as I slow down. Only while I am driving can't hear it in park or Idle. I checked the cap, rotor and vacuum lines. The noise sounds like it coming from the firewall area. Hell pa hell pa.

The problem is with the acceleration the noise part of the problem.

I would look at the vacuum lines. You may have knocked one off performing your services.
