Re: Mis fire on cyliner 1. Peugeot 206 1.4i Year 2000
You mite want to change the distributor cap or it might need a quick tune up if the distributor is damaged then it wont always spark properly witch is why u will get full 200psi if it is a continuous put put put then i would suggest getting it tuned

Hi Richard, I'm glad to help! Richard, there's a lot of things that can cause one certain cylinder to misfire. I would first: "Replace the Spark Plug and Spark Plug Wire for number 4 and see if the misfire goes away. If it doesn't then you need to do a "Compression Test" for cylinder # 4 and compare it to another cylinder and if its more then 25 Psi difference then you need to do a "Cylinder Leak Down Test" to see where you are loosing the compression. If the compression is good and you have new plug and wire and it still misfires. Then you'll need to check and make sure you have good spark coming from the coil. If you have good spark coming from the coil. Then you'll need to check and make sure the # 4 Injector is firing. Hope this helps and have an awesome day Richard.
you mean the injector # 3 was dry ? Is that injector connector plug-in, wires ok ? do anything different ? Is harness ok ? Is plug wire ok ? you need to make sure you have power thru and to #3 , even new wires can be bad ! check for a short, continuity, and good ground. any codes stored in the ECM ?
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?
A compression test should be taken at least of the # 1 cylinder to be certain that there is no mechanical mis-fire, and if the compression is good then the ignition module located under the ignition coils is most likely faulty or there could be a missing tooth on the tone ring for the crankshaft sensor. That is the DTC P0301 that you are having a problem with?
If the engine has a P0305 DTC (Data Trouble Code) for a "cylinder 5 mis-fire detected", then the first thing to do is to do a compression test to determine if the mis-fire is actually being caused by a mechanical problem, or an electronic problem.
If the engine really does have low compression on the #5 cylinder then that is caused by a mechanical mis-fire and nothing electronic will repair it, and the most common causes for a mechanical mis-fire would be a burnt or bent intake or exhaust valve, a warped cylinder head or damaged head gasket, or a damaged piston. You can call around and find a repair shop that will do a "compression leak down test" if you want to know exactly what is causing the compression leak without any dis-assembly to the engine.
Please describe miss fire? or do you mean it has a miss? cross fire occurs when plugs are firing before or after they are supposed to if it's missing then that's another issue could you please give more detail?
