98 dodge ram 1500 5.9L 2wd. Truck runs really rough, stalls, then won't start. No check engine light now. Had misfire codes, did tune up, now it still stalls and no check engine light.


What is the O2 sensor reading? If it runs rough check the engine compression, run an injector flow test and clean and replace as necessary. Check the EGR for leakage. Drive it and see if the misfire codes return, I think they will.

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

Cylinder 1 misfire detectedrich or lean air/fuel mixture fuel injecter fault and faulty crank shaft sensor


Wow... Thats a lot of diagnostic codes. First... The cyl #1 misfire will cause the Engine to run rich giving you a rich running engine. Therefore the rich lean code. This misfire on cyl #1 can also throw a crankshaft sensor code as it will slow down engine rpm. I would change the spark plug and ignition coil to cyl#1 and have the codes erased and see if that solves the problem. If not, you then need to persue any codes that may reappear.

My 1999 Chevy Cavalier has had a sluggish/weak engine. I believe the gauge is high by a couple mph, and there is a bit of a grinding when I slow down. I'm far from being any kind of adept at car m


If one of the cylinders is not producing power the engine will be very sluggish. And you should have a check engine light on which would cause you to have the computer scanned for trouble codes.
A miss will not affect engine timing.

2000 1.8 freelander wont start, had intermittent problem like a severe mis fire now wont start at all


I suggest scanned the PCM in order to know if some fault codes is stored there; note this code number for other details.

I have a 1999 buick century with a 3.1 engine stop running while driving,ran codes came back with crank sensor,multiply cylinder misfire changed crank sensor,cleared codes,will start,but idles very rough...


Did you replace the crank sensor that is in the engine block between the engine and transmission? it has two and the one by the pulley hardly ever goes bad.

Mis fires


The engine in your car is designed to run smoothly with maximum power output and produce as minimal emissions as possible. When your car's engine is not performing properly it can cause, low gas mileage, low power output, increased emissions and possible internal engine damage if left untreated. This troubleshooting guide is designed to isolate the malfunctioning cylinder and troubleshoot to repair the problem. Before we start we need to know one of two things; is the engine running poorly at idle only and seems to be ok under power? Or does the engine run fine and it's just the engine idle condition that is the problem. If your engine is idling rough please visit, engine misfires at idle If your engine cranks over but won't start visit engine wont start. If your engine won't crank over visit engine wont crank over. If your engine is running rough all of the time or intermittently you are in the right place. Below we have created a guide to aid diagnoses and repair procedure for most common rough engine running problems.

  • Step 1: Anytime you have a problem with electronically controlled components such as an engine, transmission, ABS brake, or SRS (supplemental restraint system, air bag) inspect all fuses in the under hood power distribution center and under dash fuse panels using a test light. If all fuses test ok continue to the next step.
  • Step 2: To check for problems with electronically controlled components such as an engine, transmission, ABS brake, or SRS (supplemental restraint system) and the fuses test ok a trouble code scan is needed to identify any system trouble. Use a simple scanner tool to retrieve trouble codes and check if they relate to the specific problem, like an ignition coil failure code. If a trouble code is present but does not pertain to the immediate problem like an EVAP code ignore it until a later time, after the engine is running properly. The reason we repair non-related codes after the engine is running properly is because sometime false codes can be triggered by a rough running engine. Once the engine is running properly the code present might cycle and turn itself off. You might say "if the engine isn't running right shouldn't it have a check engine light and a trouble code?" Sometimes conditions occur that will not be detected by the computer, example: if the intake or exhaust valve operation fails the computer cannot detect the failure because the problem is not sensor related, so the engine doesn't run smooth and the computer thinks everything is ok with no codes. If the trouble code retrieved relates to a cylinder misfire like an injector driver or ignition coil failure first repair these problems then re-test system. If no trouble codes are present proceed to the next step.
