Ti starving for fuel out of First gear?

[zGoldenboy]

Thanks in advance for any help......

My 95 ti sport jerks up and down coming out of first (like someone who can not drive a stick). I have to keep the gas on in order to keep going. I had a guy drive it and he said it souds like it is starving for fuel. Possible just a dirty filter? Has anyone expierenced a similar situation.

Thanks!!!! :x

Sounds like a MAF sensor. Not sure if a M42 has a MAF sensor though.
I don't think it's fuel.

Did you turn the car on for only a second or two, wait a few hours then start it up again?

I had a problem when I started the engine for only a few seconds. A few hours later it would go chug chug until I was accelerating. After a mile it was fine. But the error code I got was a bad MAF sensor. We never changed it. I guess that is what the DME thought was bad.

Best bet is to find someone with a Peake scan tool and read the fault codes.

Hi. I just want to know if there is a lot shuddering/shaking going on? It's because that's the thing that happens to may car only in first gear. Whenever I am driving between 1st and 2nd gear for a long time (being stuck in traffic, for example), everytime I come back to first gear, there would be a struggle going on. I don't really know what's the cause of it. I ask a mechanic in Firestone, and the mechanic said that a tune up would be a remedy. A simple spark plug change would do it, hopefully.

I think I have this problem as well, but with the 3.2. I had attributed it to the lack of a secondary air pump, but this doesn't really make much sense.

it only occurs when the car is 'cold'- not been started for a while. It works out within 200 ft. of driving, but sometimes it will stall on me before it works out. It can be ammusing, because it does act like fuel starvation, so you give it a bit of gas, and suddenly it's 'fixed' and launces and detaches your retinas and/or spins sideways. This is most amusing in crowded parking lots...

Once it's driving for a while, it's totally fine- about the time the air pump would have quit.

It's nearly time to have the service lights re-set again, so maybe I'll have the $tealer put it on the computer and print out the error codes for me.

I always have a check engine light because the secondary pump is missing, so I sometimes miss the 'new' problems.

when my car is cold, the power curve is very uneven. it seems to be low on power until i accelerate to about 3k rpm and then runs fine. after the engine warms up the problem goes away. this makes for some jerky acceleration sometimes. this sounds similar to your issue and i was told it could be a cold start valve (or equivalent). i havent done anything for it yet.

another issue i have that happens in stop and go traffic in first gear is what seems to be the clutch chattering. this is probably my own fault, but sometimes when i slip the clutch a little longer than i should it chatters and makes the whole car vibrate.

and the M42 has a mass air flow meter, not a sensor with the heated wire or air density sensor and all. its simply just a flap in the wind. ive seen upgrades for the sensor but they're pretty pricey.

96 318ti has this problem too, but it does it to me when I have the AC running and the engine is warm, it is VERY annoying =/. Any advice?
