#15 of 21 Very bad jerking and ticking by doug01 Apr 18, 2008 (8:47 am)
I have a 01 z71 tahoe with the 5.3L. The vehicle runs ok under very low load and idles fine. When i try to accellerate the vehicle jerks like i am flooring the gas and then letting off. The engine is also ticking very bad (sounds like a vehicle totally out of timing). I am lucky to get it up to 65 or 70 on the highway... Any ideas? I am thinking maybe the camshaft positioning sensor, but i am not sure. I hate to just start replacing items.. Thanks for your input. Replies to this message: kiawah (Apr 18, 2008 9:29 am)

Replying to: doug01 (Apr 18, 2008 8:47 am) Your symptoms with loud ticking could indicate a more major problem, bad valve or camshaft. I'd get it looked at before you have portentially more serious damage done by that problem deteriorating.

Replying to: dangar64 (Feb 18, 2008 5:44 am) I have a 04 Suburban that did the exact same thing on a trip to Florida. I also took it to Autozone and the said I had a lean code on Oxygen sensor. I found in other forums that this is happening when fuel tank is between 1/2 and E. Therefore I filled up every time we stopped on way back and did not have stalls on 770 mile trip. I would like to know what is causing this problem. I need help also. Replies to this message: jamelt (Jul 27, 2009 2:49 pm)

Replying to: roblisasmith (Jun 07, 2008 6:56 pm) I had this same problem on my 2002 Chev Suburban 1/2 ton, V8. What happens is the solenoid next to the gas tank doesn't release the vacuum created in the gas tank after you have been driving for long time without stopping. If it stops on you just get out and unscrew the gas cap. If you hear a release of the suction then that is your problem. The dealership can hook up your vehicle to a computer and tell you if this is your problem.
#20 of 21 97 Tahoe want start by accrdjdm Oct 05, 2009 (5:12 pm)
I have a 97 tahoe with the 5.7L motor. It started missing while driving down the road. and then cut off. Code P1345, came up, Manufacture control error. Replaced Distributor, new computer and new cam sensor. Fuel pump comes on and theres fuel at the top of the intake. But the is no gas to the injectors. If you put a little gas in the throttle body it will fire up. But when its going it dies. Please Help! Thanks

Replying to: dangar64 (Feb 18, 2008 5:44 am) I just experienced my 03 Yukon stalling on me today. I was at a stop sign and when I went to gas up to cross the street, the car started to jerk back and forth and had problems accelerating. I was right in the middle of the 4 lane street and this was a very scary experience. I put the gear in park and turned the car off. The car sounded fine when it started up again so I stepped on the gas pedal, but then it started jerking again. The steering wheel locked up on me, the car stalled, engine died, and I put it in park and started up the car again. I noticed that everytime when I would come to a reduced speed, the engine would die and the steering wheel would lock up on me. Has anyone had this problem before? Please help me?
