Hi guys. Basically I have a 1994 non-sc'd bonnveille. After heating up (driving for more than approx 20 minutes) my car sputters bad after leaving a complete stop. once i get up to about 5mph the car runs fine. no problems.

I have swapped out the air filter (fram), the sparkplugs (ngk tr-55'*) and wires (ngk as well).

I read a few columns suggesting that maybe a mass air flow sensor may need replacing. But at 150$ Id rather see if there is any other options before doing so.

Thanks so much in advance!!

try unplugging the MAF sensor (it may not run as well as normal, but you will be able to tell if it fixes the stumble)

That simple eh? I have to tell you guys, you guys ROCK!!

ok so I unplugged it and was a little un-nerved as the check engine and traction control lights jumped right on. But that has to be the factor.

you see, i bought the car recently so i have NEVER realized how much power this guy has. Once I unplugged that sensor my car seriously drove like a bat out of (you know). I am absoloutly SHOCKED on how well it ran once the sensor was unplugged. Is it safe to drive like this until I can get it fixed in a week or so?

Thank sooooo much!!!!!

You may be able to avoid replacing the MAF by spray cleaning it with CRC MAF Cleaner (A'zone carries it). If you take it out, you will see 2 tiny, delicate wires in the passage. Those are what need to be spray cleaned.
You are right. These guys definitely rock. This is one of the greatest spots I know of.

Awesome! I'll pick some up on my way home tomorrow and get back with the results. Thanks!

Picked up the exact Item at a local checkers. It was a horrible day.

First I shut the door on my finger 3 DIFFERENT TIMES IN THE SAME PLACE.. (stupid wind)

Then, while re-programming my keyfob (thanks to you guys and your supreme knowledge again) I locked my keys in the car.!!!

But luckily (thanks to you guys yet again) I was able to use a screwdriver and a broken shelf to get them out.

THEN when I FINALLY get to pull the sensor out. I place it in the engine bay. And the wind knocks the hood close BREAKING OFF A SMALL CHUNK OF PLASTIC from my MAF!!!!!!!!!!!!!!!!!!

When all this set in I went back, sprayed the sensor, and put it back with no hope of it working at all.

Fired it up and what do you know. despite the fact that a small part broke off it works like brand new.

Seriously, you guys made driving this car fun for the first time. I can't thank you enough

I've had days go like that before. But...
Yeahhh! Glad to hear it ended w/ some good news.

Same thing happened to me today. My MAF was faulty (took me a while to realize it) and I replaced it today. $173 later my Bonnie runs like a brand new Secretariat.
