Hesitating and Lurching when Accelerating or Decelerating
Have a 98 4runner, manual transmission, and it has been hesitating when accelerating and lurching when I take my foot off the gas. Just replaced the plugs, wires, and coils and it was fine for about a day and then it came back. Thoughts on what to check next? No CEL. Normal idle. Seems to come on after it warms up and lightly at first then seems to get worse. Sometimes seems to go away though. Acceleration is fine once it does go but is a heavy thump, likely the drive shaft maybe when it does finally accelerate.
A few weeks back replaced:
- fuel pump
- fuel filter
- alternator
- power steering pump
- belts
- water pump
- timing belt
- thermostat
- oil/filter
- coolant
Past few days replaced/did:
- plugs
- wires
- coils
- 1 can of fuel system cleaner in the gas tank
- MAF sensor cleaned with MAF cleaner
- air filter
- felt/looked at vacuum lines and all look good at least
Appreciate any thoughts!
