Cylinder 1 is not firing or is intermittently firing. Check the output on the coil associated with #1 cylinder by using a spare plug attached to #1 wire while engine is running. If it has good spark, check the fuel injector for possible problems. Crank shaft sensor would not be the problem as the engine has to have it to run. You may need to have it checked further at a reputable repair shop as this can get more involved than a back yard repair.

Reduce engine power light comes on 2005 buick lacross


The check engine light n or reduced power light comes on when the on-board computer detects a fault in engine driveability or performance, transmission control system or transmission, or the emissions system, and a fault code is set and stored in the computer. Faults that can set the check engine light can range from a vaccuum leak, engine mis-fire, low engine compression, faulty sensor such as O2 sensor or other engine sensor, hydraulic pressure loss in transmission, transmission shift solenoid, open/short in wiring harness, emission evaporative system leak, or one of over a hundred different reasons. The only way to know what set a fault code and turned the check engine light on is to have a diagnostic scanner hooked up to the on-board computer and read it for stored diagnostic fault codes. Many auto parts stores will do this service for free- (like auto zone)check with you local parts stores. If none in your area do, then you will have to take it to a shop and pay to have the computer read for stored fault codes. Without knowing the fault codes numbers, it would be irresponsible to guess as to the cause as there are hundreds of possible causes.

Gas mileage is terrible,check engine light on,put on computer by friend said o2 sensor -i wasnt sure my friend new what he was doing so took to auto zone now they say the computer wont read


auto zone reader will sometimes not read codes. take it to your local garage and ask them to plug into it with an updated reader. i dont charge to read a code and i would hope they dont either. the o2 sensor could cause bad gas mileage. whens the last tune up done? check air filter. plugs? also check air in tires. low tires can cost fuel mileage as well. hope this helps

I have a '03 Toyota Celica GT-S with a annoying mis-fire. Started small by replacing all spark plugs - nothing. Replaced the MAF sensor - nothing. Took it to a authorized toyota shop & checked...


Replaced the MAF sensor - nothing. Took it to a authorized toyota shop & checked compression which check out good and put the computer on. Computer read mis-fire on cylinder 1, and then multiple misfire (like it would jump around). We went ahead and replaced the fuel injector on cylnder 1 - did not solve problem as when we hook the computer up, misfire seemed tp stay at idle and seem better when running high RMP, but check engine light is on as it never went away. Went ahead and replaced the coil pack to cylinder 1 - nothing. what am i missing?

My car didnt start so i took it to auto zone to get hook on the diagnostic machine it showed need a cam shaft and crank shaft sensor i got them replace and a week later the same problem car will not start...


Does the vehicle run at all with the new sensors?? If it does and experiences stalls or hard starts, read the following. When replacing cam or crank sensors, the vehicle's computer must go through a "RELEARN PROCESS". This can only be done at a authorized GM dealer, and usually costs $130+. I'm not sure if your vehicle has been properly diagnosed, but very rare does both crank and cam sensors fail simultaniously. This problem may be beyond what has been diagnosed, If the relearn process don't work, this issue needs to be re-diagnosed by another tech.

What does the check engine light indicate.


When lit, the computer has found some type of problem with the engine computer system, often a bad sensor, or something electrical with the ignition, such as mis-fires, running rich/lean, etc. Auto Zone can find out why the light is on, by hooking up a OBD II diagnostic reader, to retrieve the code, that is associated with the paticular sensor.

O2 Sensors


Autozone oxygen sensors do not function properly in Toyota vehicles. Just had a Tacoma yesterday with the same issue. New sensors, runs poor, check engine light on. Toyota sensors fixed it right now.
