Check the Fuel Pump and Fuel Filter. Sounds like 1 Or Both are Bad.

2001 Chevy Silverado 1500 4.3L V6 was running fine and then the O2 Sensors went out. I have since replaced them but it with start then idle really rough then die if you let off the gas


Robert, have vehicle scanned for diagnostic codes. Check for vacuum leaks and if you have not done recently give vehicle a complete tune up cap,rottor,wires,plugs,filter's,etc, including injector/throttle body cleaning. Check the attached links,instruction and guides, Good luck

How do i complete the drive cycle in a 2004 Lincoln LS


A complete driving cycle should perform diagnostics on all systems. A complete driving cycle can be done in under fifteen minutes.
To perform an OBDII Driving cycle do the following:
  1. Cold Start. In order to be classified as a cold start the engine coolant temperature must be below 50°C (122°F) and within 6°C (11°F) of the ambient air temperature at startup. Do not leave the key on prior to the cold start or the heated oxygen sensor diagnostic may not run.
  2. Idle. The engine must be run for two and a half minutes with the air conditioner on and rear defroster on. The more electrical load you can apply the better. This will test the O2 heater, Passive Air, Purge "No Flow", Misfire and if closed loop is achieved, Fuel Trim.
  3. Accelerate. Turn off the air conditioner and all the other loads and apply half throttle until 88km/hr (55mph) is reached. During this time the Misfire, Fuel Trim, and Purge Flow diagnostics will be performed.
  4. Hold Steady Speed. Hold a steady speed of 88km/hr (55mph) for 3 minutes. During this time the O2 response, air Intrusive, EGR, Purge, Misfire, and Fuel Trim diagnostics will be performed.
  5. Decelerate. Let off the accelerator pedal. Do not shift, touch the brake or clutch. It is important to let the vehicle coast along gradually slowing down to 32km/hr (20 mph). During this time the EGR, Purge and Fuel Trim diagnostics will be performed.
  6. Accelerate. Accelerate at 3/4 throttle until 88-96 km/hr (55-60mph). This will perform the same diagnostics as in step 3.
  7. Hold Steady Speed. Hold a steady speed of 88km/hr (55mph) for five minutes. During this time, in addition to the diagnostics performed in step 4, the catalyst monitor diagnostics will be performed. If the catalyst is marginal or the battery has been disconnected, it may take 5 complete driving cycles to determine the state of the catalyst.
  8. Decelerate. This will perform the same diagnostics as in step 5. Again, don't press the clutch or brakes or shift gears.

A mechanic falsifying indications to justify big engine work...How can I tell?


I suggest a second opinion would be in order as everything he did for the tune up was not altogether necessary. I consider that as the car was running ok before I would not touch the carby other than to fine tune the idle mixture to emission requirements. Any problems with the distributor cap would have showed up as a miss and the rotor button would have to be really bad but again as it was running ok. My policy is don't touch what ain't broke.Power valves in carbys are there to give extra fuel when the vacuum falls off under acceleration and do nothing else. To accommodate a bigger alternator more adjustment on the idle mixture screw would be necessary at idle but as alternator barely charge at idle the adjustment would be little. The low compressions may be from pumped up hydraulic followers and I would discuss that with the original engine builder as to what hydraulic units he fitted. but again if it was running ok before what the hell. Yes get a second opinion for sure from the engine builder.

Shuts down going down the road shuts off completely


vehicle shuts down while driving down road and does not start backup for at least 20 minutes, could be a bad crank sensor. if bad it will start and run fine, but it will keep shutting down until fixed.

My 2000 ford explorer runs rough when started after sitting for a while but once i drive down the road for ten to fifteen minutes it runs better.


Have a mechanic check your idle bypass valve, since it may be bad
or need cleaning, also, have a tune-up done, if you haven't had one in
the past 30K miles. Good luck.

2000 grand am- wont stay running


It Sounds Like A Fuel Supply Problem. Which Means It Might Be Your Fuel Pump. Check Your Fuse's And Battery Connections Before You Start Getting Into Dropping The Tank And Replacing It.. I Had A 94 mercury That Would Run In The Winter But Would Shut Off While Im Driving Down The Road In The Summer. When It Would Shut Off I'd Listen To My Car. Turn The Key On For 4 Seconds And Off for 2 and Have Someone Listening To The Gas Tank. The Pump Should Make A Constant Tone. If The Tone Changes up and down or if you hear grinding. theres your problem. a basic electric fuel pump for a car should turn on for 3-5 seconds and shut off when you turn the key on. NOT STARTING IT.
