    Hey everybody! I had recently just went through hell to get my new clutch and shifter but it's finally done! But before i had the problems with the clutch, i noticed that my car was starting to jerk a little bit when i would give it some gas. When everything was fixed it really didn't seem to have that problem anymore. But now from driving it the past couple weeks it has started to jerk like never before. And i mean jerking like throwing me back and forth and not wanting to gimmie gas to go! Even when im at a red light and it turns green i put my foot off the cluth and go into first but its like it wants to bog out. It hardly will go and then out of nowhere it will pick up and start driving fast. But once that happens then throughout almost every gear i get the car jerking everytime i try to give it gas. But if i hold the petal all the way down it will start to pick up. Can anybody help me out and let me know what you think my problem would be? Or where to start to try and figure out what the problem is!

    Thanks a lot!

    Sounds likely that the intake boot is torn and when the engine rocks back from load, it opens the tear allowing in unmetered air, making the car lean; therefore not as much fuel is sprayed, the car bogs, engine rocks forward, closes tear and cycle repeats. I have seen it before, these MAF/VAF cars hate unmetered air.

    Is the Intake Boot the same thing as a Intake Coupler?

    I had the same thing happen to me when a spark plug wire got cut somehow on my old 1.9. Engine would buck to the point where I thought for sure it was going to break a engine/trans mount. Not a good feeling

    The intake boot is the large diameter rubber duct running from the air cleaner to the throttle body. I think its almost 3" in diameter.

    Would a bad throttle position sensor cause the symptoms? I dont know, since I havent (yet) had a bad TPS that I know of.

    bucking from a dead stop is usually the spark plug wires. mine is not a 5 speed so I didn't get the bucking problem but a very low idle in gear. just changed mine today and it runs so much better
