If you can see the MAF wire/s I would try a spray cleaner. It just might save you the price of a new one.

replaced MAF and plugs. still very bad hesitation and the motor will not spin above 4500 rpms. Any ideas? Maybe because i replace the MAF after the plugs, the car ran lean or rich and fouled the plugs again?

Didn't read all this but your car runs just like my C5 did with a bad o2 sensor. Any codes?

vince3

air/fuel code
o2 codes


there is a recall on my ecm that has a problem and it has a trouble code at all 4 o2 sensors because of it.

vince3

so your c5 wouldnt spin above 4k and ran pretty rough? Did it throw any misfire codes?

Would miss really bad and had missfire codes and 02 codes. I had an 02 sensor touching my headers. The thing that sucked is I replaced them and didn't think it fixed it. Then after spending more money I found the 02 sensor fuse was blown. I also had replaced MAF. Do you think you could have damaged the 02 sensor with all the extra exhaust smoke?

i guess it is possible. I wonder how if i could tell if it is a misfire vs o2 sensor?

Change the oil. It not running right if you have seafoam in your MAF Clean it carefully with alcohol. Then you should be ok,
Should have ask the forum on this first!

Carroll Shelby recommends and uses Z-Max in all of his cars.

Leprkon

just an idea here.. did you disconnect the battery before you cleaned the MAF ? might help to re-zero the air flow memory.

Seafoam is liquid magic!!!!! I use it in every engine, Audi FSI, LS1, Mercedes, Japanese engines. Works good in the fuel line, but amazing directly into the intake. I've never used it in the engine, which could be abit tricky since you'll have to keep changing the oil filter to get all the sludge out.

Did I mention how good this stuff works.

I used Seafoam in my 1997 GMC pickup with a 5.7L V8. When it had probably 90,000 miles on the engine, I added it when I filled up with a tank of gas. Before too long, it began spewing black stuff out the exhaust and it fouled up my O2 sensors. It ran very rough/misfired/stumbled until I replaced those sensors. One I had to replace twice until it got all of that stuff out of its system.

Not going to do it again.

Same situation with those oiled filters. If you over oil you can ruin the MAF.

Like Slick 50 and Duralube?

I use Seafoam once a year on my Yamaha 2 stroke outboard. It really does decarb the motor and clean it out. But, I always clean the O2 sensor and change the plugs AFTER using it. It frees up all of the carbon and deposits which in turn foul the plugs and O2 sensor.

Some of you guys are making me nervous. I used SeaFoam for a fuel stabilizer last fall, 1 ounce per gallon.

You can try cleaning your MAF sensor. Good Luck.

Thank goodness I never really had the urge or need to do that to my Corvette or any other car.
