hi all, i recently got 2 of my valve guides replaced on cylinder 4. when i got the car back i noticed ther was stil a bit of a miss when i was taking off so my mechanic that done the valve guides told me it was probably the plug on cylinder 4 that needed replacing so i replaced it and it went fine for the day but eventually the miss came back worse and worse, and now it has become a dead miss you can hear it when the car is ticking over! now the power seems fine but im just wondering did the mechanic make some sort of a mistake when he was doing the valve guides or is there something else gone wrong?? the car is a 99 with 90k miles on the clock. thanks for any inputs

 

Just curious, what made you want to replace just two valve guides?

 

What wut?

ticking over?

Is it making a ticking noise when idling?

If yes, check/replace your TCT.

 

he said just two were worn.. should he have done the 4 of them? and what is a tct

 

Timing chain tensioner, do a search.

 

wel that might be the ticking but the miss is what iam really worried about if any1 has any suggestions!!

 

How do you know it's missing?

 

i have heard more misfires and timing chain tensioner probs. here on this forum than my g/f's bitching at me. How many issues are really misfire or bad tensioner?

 

you can hear the miss in it when its ticking over, and when you accelerate from 1500 - 2500 it misses like crazy.. iv done the search but they al have cel lights and i dont...

 

so it's not a miss
