Well spark plugs are supposed to only last 30,000 miles due to the fact that they are the cheap Champion Coppers. If you change your plugs buy the cheap champion coppers again because alot of people are having problems with other plugs. You have 16 btw.

Make sure your air filter is clean.
PVC valve make sure it moves freely
TB cleaning/Grounding it also helps
Seafoam isnt a part of a tune up but it does get rid of debris

 

Started at 7 this morning and just got done at 11 with a tune up. Replaced the plugs, egr valve, grounded the throttle body with 10awg wire and cleaned my pcv valve. After 86K miles my plugs were burnt down to .055 gap. Took it out for a spin around the block and what a difference on throttle response. Also I did not notice it surging anymore.

I want to thank willdikem66 and everyone else that helped.

 

Spoke too soon. On the way to the lease it started doing the same thing. If I start to slow down just a little it will slow down then surge for a second. Also one time it started missing real bad then went away.

Could it be bad gas?

 

I would hope not that bad of gas, Plugs are supposed to be at .44

 

The new ones are .044 the old ones were so bad they were at .055.

Any idea what to look at now. Its not throwing any codes.

 

wait for a code it will come grasshopper

 

Yeah pretty much just wait that is the only good thing atleast the computer will point you in the right direction

 

Throttle position sensor? Maybe a bad spark plug wire arcing? Ignition coil? How's your compression? You might want to have that checked.

 

did you do wires and boots and springs on the coil packs?

 

There is no wires, boots are made straight to coil pack. Did not know the boots could be changed.
