Jetta V5 125 kw hesitation problems (2002 model)

2002 hyundai accent , gas or Diesel NO VIN posted.
no engine told at all and is a pure engine quesiton.
no vin told or country. (so books on it can be read)
the misfire can be lots things.
why not scan the PCM first and see P03xx errors. or more.
the gen2 model came new with one of these,nobody can guess.
the engine is MISFIRING, sure power loss, sure.
the first question is do all 4 cylinders misfire or just 1 or 2
facts and test matter on all engine diagnosis, guessing fails. hard.
if that oil leak did not leak in to COP spark wells the leak is a SIDE SHOW to nowhere. oK, no COPS on a DIESEL.
misfire is engine bad, spark bad,and fueling bad. in that roder
if all fail, the cam belt slipped at 100k miles. on 1.6L ,no me looking them all up now. no engine told

• Cam belt ignored for 20 years, no way !
• VVT bad.
• heat gasket blown.
• valves burnt in head.
• spark plugs or cops boots or all 8 parts
• valves ping broke(head)
• coolant leaks to combustion chambers for the bad act of using only water for AF antifreeze 50% correct.
• these are not gessing those are legit failure mode, 20 or more possible inside the engine or attached.
• injectrors bad or clogged.partly or leaking
• fuel pressure 2 time normal and FPR stuck closed and bad.
• or stuck one and too low fuel pressure. or fuel pump bad.
• I can to more, but this list shows why we do tests and not guess. buy the tools or get the car fixed by shops with tools

engine compression way low x4. <150psi , cam belt slipped.
spark tested bad, any and all Hyundai engines are interference..
that means if cam is belt driven and ignored, it can bend valves
easy as pistons hit(crash-into) head valves.$$$$$$$$$$$$$$$$

check to make sure the battery is tight on pos. And Neg. post

why not have them reset in a bosch specialist garage ,cost about 120 euros each

this is the engine electonics lamp or eml, basically covers upto 2000 different codes, if it hasnt gone out its a permanent fault but if the car is driving ok not too serious if its major (petrol models) the lamp will flash. Refer to a good garage/ vw agent or specialized in diagnostics to fix.

yes!!!!!!!!

Has the car been serviced recently?
If not I would suggest getting it done.Not sure if you have diesel or petrol, but oil can thicken causing more load on the motor and airfilters get blocked and can cause a rich fuel mixture.

If petrol you can take out the plugs to check if they are a light brown colour, if very dark or black you need to check and adjust carb/injection settings/filter.Need to know what engine it is really.

check the pressure inside the tires and verify the values from the original one which are on the fuel cover sticker. if it's good check if the steering is stable on raod with sppeds more than 70 to 80 km/h

Sounds like its missing on 1 or more cylinders. A check of the plugs and wires is in order, Could be a fouled plug or a loose/bad sparkplug wire. Best of luck.

well will it start using a little shot of starting fluid ? if so you might have a weak pump . try this and see . thanks Jerry
