94 SSE DOESN'T HAVE QUICK THROTTLE RESPONSE

[94BONNE]

94 SSE 180,000 km stock with new plugs.Engine doesn't respond well to quick acceleration and it has some pinging and also rough idle when stopped at traffic lights with brake applied.Any help on these problems would be appreciated.

check your maf sensor and clean with maf cleaner if needed also check for vacuum leaks everywhere you can... then post back here.

Give this a shot and we will go from there...Only remove the throttle body if you feel comfortable doing so or have the mechanical abilities.

Okay I'll give that a shot and post back the results.Thanks for the info.

also checking your fuel pressure might be a good idea...

ok i'd also look at the idle air control valve. seen these symptoms caused by that.
just a thought

Seafoam cleanout might help also.

Edited for new, updated maintenance list:

• Clean TB http://www.pontiacbonnevilleclub.com/fo ... =48&t=1661
  Run seafoam through gasoline and intake.
  
  Then check to make sure your maintenance is up to date.
  
  Grease: Ball Joints, Tie Rods Every 8-10k (Synthetic grease if you've got it)
  Air Filter Every 15k (Amsoil Ea, Purolator PureONE)
  PCV Valve Every 15k
  MAF Sensor Element Cleaning Every 15k http://www.pontiacbonnevilleclub.com/fo ... =48&t=1661
  Fuel Filter Every 12-15k (Purolator, AC Delco, WIX)
  Spark Plugs Every 30k (NGK TR55 or Autolite) (Never Bosch)
  Ignition Wires Every 30k (Napa Belden, AC Delco, Autolite, NGK) (Never Bosch)
  Oil & Filter Every 5-6k (Mobil1 and Purolator PureONE) (Never Fram) http://www.pontiacbonnevilleclub.com/fo ... f=45&t=214
  *Conventional Oil Every 3k(Pennzoil with a WIX (Napa), Delco or Purolator filter)
  Transmission Flush Every 15-20k (Always make sure filter is changed when flushed)
  Cooling System Flush Every 25k (Peak or Prestone Green Coolant Only) (Never Dexcool)
  Oxygen Sensor Every 80-100k (30k for non-heated) (AC Delco or Denso) (Absolutely never Bosch)
  
  *Special Considerations*
  All 3800s, LG3, LN3, L27, L36, L26, L67 & L32, especially important on vehicles factory installed with orange Havoline Dexcool Antifreeze/Coolant:
  Lower Intake Manifold Gasket Replacement, every 80-100k (ignorance of this can allow coolant to enter your engine oil, this happening can cause irreversible lower engine damage, requiring replacement of subject engine)
  
  Series II, Naturally Aspirated, RPO:L36:
  Upper Intake Manifold Plenum Replacement, every 80-100k (ignorance of this can allow coolant to enter your intake manifold, possible damage to occur can be hydrolock, irreversible damage to emissions devices, misfires, etc. Most times, engine replacement is required if ignored long enough.)

Clean TB
Run seafoam through gasoline and intake.
