The engine of my car seems to be lagging behind lately. I know my VIAS is broken, but my car seems like it is missing low-mid range torque. The engine also isnt as linear as it was before. It's almost like there is a miss present. My plugs have 20k miles on them and I have a clean filter. I am going to clean the TB and run some Seafoam thru the engine to see if it clears up the problem. Otherwise, I suspect that the coils are going bad. Anyone have any other ideas.

 

lots of stuff, clean TB, fuel filter change, MAF clean-up/replace are common things to check. Does it do it when its cold?

 

to me it kinda sounds like the coils are going bad. if thats the case i got em for 265 shipped to your door and they are the updated coils. Is your check engine light on?

 

If your car is warm and you notice a drop in power after 3500 RPM, it is most likely your MAF.

 

Car has newer copper plugs, changed the Fuel Filter a while back, clean JWT, recent PCV. All I can think of is cleaning the TB. The car isnt throwing any codes and it feels sluggish cold or warm.

 

itll probably start throwing codes soon..where did you get the 6 ignition coils for 265 shipped? do u know around how much shops charge to install them? i should be going to autozone to see if theres a problem with the coils for my car...code 1320 supposedly

 

in the FS area here they are $265, you can ocasionally find them cheaper on ebay.

I sat coils or MAF

From everything I've read/heard, the platinum plugs perform best in our car. Of course, I imagine that frequent replacement of copper plugs should be sufficient - have you checked the plugs?

If the car is missing it'll throw codes.

If there is a maf problem - then it won't necessarily. How does it run at WOT? If it runs fine at WOT but sluggish below maybe it is maf or coils or air getting in behind the maf in your intake.
