My Tubi Exhast has no cats so I can skip tha cats being clogged.

So im down to 02, MAF, Coil Packs, & Plugs. What can the estimated cost be to replace all of them?

 

As stated above, MAFs can be cleaned by you with CRC MAF cleaner aerosol. Plugs and coil packs will be done at the same time, about 3-4 hrs. labor, plugs cheap, packs about $60-90 each for stock, $150 each for HEs. O2 sensors, don't know. Anybody? Please correct if my prices are wrong. Pretty sure I'm in the ballpark. BTW, I would def. go to a good indie for these repairs. P really doesn't need to know.

 

I will throw 2 more in, fuel filter and I have been told that the lwfl needs to have the computer reprogramed for it but I always thought it was for idle issues.

Good luck and please let us know what you find

 

It's most likely the plugs. I had the same issue.

 

What did it cost you to have the plugs replaced?

Why did your plugs get fouled up? Race Gas?

 

you getting a check engine light,, I would think if it was engine related it would throw a code.

 

No CEL, No Codes

 

If it has anything to do with emissions it should throw a code.

 

Not if he's had a reflash. His OBD warnings for a catless exhaust have been programmed out.

 

I think plug replacement jobs run about $800 or so.

My plugs just went bad from my car being tuned. Stock plugs on tuned cars will go bad. I had about 17k on my car when the plugs went bad. How many miles on your tt?

 

I'm sure the plugs and/or MAF are fouled if you ran leaded race gas. Datalog it and be sure.
Agree with Bobby, with the flash and catless exhaust the o2 sensors are probably turned off.

 

I can also vouch for the MAF cleaning, it made a noticeable difference, I did mine at 22k recently. Easy to do, hoses pull off and go on without headache.

if your using an OEM filter this might not be necessary however if you have been using a high flow oiled filter those thing let enough crap through to dirty up the MAF.

 

I have 11,500 miles on it. What needs to be removed to change the plugs? Rear Bumper, Rear Tires. ???

The shop wants to replace my 02 sensors but if the Evo tune had them off then there is no reason to bother with them.

Most shops drop the engine a little to get access, but a DIY is listed above (thank you eclou.)

 

post cat sensors are off or adjusted, but precat might not be? Leaded gas can kill them regardless.

I had my plugs changed near the 20k mark with a tune but they actually looked pretty good but I dont track the car nor driver it that hard. After my MAF clean 3rd and 4th grear pulls were noticeably stronger. Easy 1 hr job max.

Plugs will run you $800 to $1200 depending on your stealership.
