I have a 1999 Nissan Frontier V6 3.3L. I had my timing belt and water pump changed last week and my car has been giving me two problems since. 1. I have a very rough idle and 2. My check engine light is giving me a code p0300 which is a random misfire. What is going on and how do I fix it?
Timing Belt and Water pump issues?
A random misfire will give you a rough idle. I hope the mechanic installed the belt correctly or the cam timing will be way off. Look to see if any plug wires are broken at the ends and just stuck onto the plug or cap if it has wires. The timing marks on the cam and crank have to be lined up correctly or the valves will open at the wrong time causing all kinds of problems, even bent valves. Take it back to whoever worked on it.
Timing Belt and Water pump issues?
sounds like the timing belt isnt put on right, its probably off a tooth or 2. what probably happened when whoever put the belt on, the cam moved with them and through the timing off. thats why your suppose to put something in the guage hole of the cam to keep it from moving, until you get the belt on. better be checking that timing.
Nissan 3.0 and 3.3 engines are really hard to purge the air out of the cooling system, sometimes this procedure can take up to a half an hour. Chances are likely that when the technician replaced the water pump and timing belt he removed and replaced the ignition wires. These wires are 7mm wires and will only last up to 100 thou miles, you are now getting either cross fire from the wires or shorting to ground. Take it back to whoever did the work and have them fix the problem, do not let them charge you labor and do not use after market wires.
yes who did the work on it take back and tale them what it is doing before it becomes worse.
have it pulled back to who did work dont run it and tell them to place belt on right way this time. its off a tooth or so. one tooth is all it takes to cause misfire. if it had distribitor you could turn it one way or another and correct problem but im guessing its got a ignition module. wich means timing belt has to be moved to right tooth.
