Strange problem. Here's the situation. 2001 Tib, Auto, only mod is I removed the air duct and resonator. I'm sitting at a stop light, in drive, foot on the brake, car's running fine. Light turns green and I press the gas peddle and then my engine bogs down like it's going to die, sputters, then takes off like normal. It doesn't do this all the time, but it happens like 3 out of 5 times. It only does this when I'm taking off from a stop and I'm not hot rodding it or anything.

Normally I wouldn't be too concerned but I'm about to drive to Salt Lake City for a few days and that's like a 9 hour drive. The last thing I need is my car breaking down hundreds of miles from home.

Any suggestions?

 

Check the airflow direction arrow on your MAF. it should be pointing towards the back passenger side/towards the TB.

 

You might want to swap out the plugs for new ones. I just had a similar problem with my 01 and that cleared it right up. It's a cheap fix and does'nt take long at all. smile.gif

 

Is you IAT sensor still connected or is that just hung in your bay?

 

Sorry for the delay guys.

MAF sensor was never touched, it still faces the right direction.
I suspected the spark plugs from the start, but I don't have a grippy spark plug socket nor a magnet to pull them would with. But I'm working on that.
And I never had to remove the air box/filter box so the sensor is still in place.

Thanks for the help guys.

 

Just and FYI, plugs and wire *should" be checked around 40k's or so, how many miles / kilometers do you have?
But yeah, plugs and take a look at your wires, if you see like a "white arc" on them (the end where it goes into your engine and connects to your plugs), its time to replace them

 

just get new plugs/wires anyways..can't hurt.
plus i'm sure (almost positive) that your problem is your spark plugs. whenever you take off from a stop it seems like you "get stuck" for a few seconds? same exact thing happened to me, it's definitely the plugs. fork out the $40 and get some NGK iridiums and a wire set, you won't need to replace plugs for a long time, the NGK's will burn off most of the bad stuff that a normal spark plug would foul on.

 

I've got 56k miles, and from the maintence I've done on it I can tell the preivous owner (I suspect a lease return) didn't do crap for maintence.

I'll get the spark plugs changed tomorrow and maybe if I can get a good deal, the wires too. I'll let you all know how it goes.

 

Iridiums suck for the price... good old $2.50 coppers will do the job just as well, last half as long, and are 500% cheaper.

 

if geting to plugs don't fix it then, check your FPR.. lot of times if a car boggs down, and acts like it going to die, that might be it..
