MAF Sensor '97 GT 3800

[Rob D.]

I have read through a couple of threads about DIY and i thought i would give it shot cause i can't bring myself to spending the $500 to get it replaced at the shop. Before i actually go out and get the part, are there any things that i should be extremely careful about when installing this sensor myself?

Thanks

Welcome to AF.

$500 at a shop.......RIP!!!!!

Easy as making pie. Almost plug and play. All you will need is a Torx safety tool/driver hat fits the only two screws that hold it on to the throttle body. Make sure ignition is off or you can disconnect the battery negative as an extra precaution. Your choice.

If you have an SES light you may need to get the PCM reset. But any DTCs should clear after a few drive cycles. Good luck.

I'd punch the shop owner/stealership service writer in the head if they quoted me that rediculous price . The sensor runs less than $150, and like bnaylor said, takes 5 minutes or less to change!!!!! If you have an Auto-Zone or Advance in town, they will reset the CEL for you for free.

Thanks for the help guys. I just checked around and the part sells around $150 as already mentioned. Now i'll just have to find someone that has that torx safety driver????

So that SES will clear after i drive it around a few times?

Great!!

Any decent auto parts store will have the tool, and it should be less than $5.

Also, make sure you get what is classified as a new MAF sensor, preferably the OEM GM one. The remanufactured ones like A1 Cardone and Niehoff leave alot to be desired and may be bad out of the box leading you to believe the MAF sensor is not the problem. Not uncommon to go through more than one until you get a good one.

Sears has the Torx safety bits and other Torx bits.

Got the sensor replaced this weekend and everything runs smoothly. SES light has come off and no more rough idling. Thanks for the help guys, saved me $350. Going to try the front brake pads this week. This DIY thing can really save you some money.

You could've actually ordered a brand new oem from zzperformance.com for only $120.

I thought the new GM MAFs at ZZP are for '99 and up models only. If you have a '97 or '98 you are SOL. But that price at ZZP is great. We have AC Delco sources that match ZZP's prices on other year models. Just an FYI.

Oh my fault. I bought one from them but I got a '00. Didn't look to see what all years they had.
