What are the probable causes of recurrent DTC P0302?


Check the compression on the cylinder. Compare it to specs and to the other cylinders. If the compression is too low, it can cause misfiring. Low compression could be due to piston ring wear, cylinder wall wear, or improper valve seating.

Rough idle jetta 2001 1.8t when it's cold codes p0300 and p0302


p 0300 is random misfires and 0302 is no 2 cylinder misfire
most misfires are from dirty injectors rather than plugs
run a quality injector cleaner and see if there is improvement

Missing,viborating


Misfire could be a number of things:
a) spark plugs - change them if used over 15K miles - inspect/regap.
b) spark plug wires - change them if over 15K miles - inspect
c) ECM (electronic control module) - test with HEI (high energy ignition) tester.

The vibrating tells me that the engine is running on less than its normal compliment of cylinders - the shaking is produced by the imbalance caused in the engine by one (or more) cylinder(s)
not firing at all.

The "Check Engine" light probably is coming on due the the misfire condition. Go to Pep Boys or
Advance Auto Pats, where they'll tell you (free) your codes causing the "Check Engine' light to be
lit - the code coming from your truck's computer will probably be one or more of:
P0300 - Random/Multiple Cylinder misfire detected
P0301 - Cylinder 1 misfire detected
P0302 - Cylinder 2 misfire detected
P0303 - Cylinder 3 misfire detected
P0304 - Cylinder 4 misfire detected
P0305 - Cylinder 5 misfire detected
P0306 - Cylinder 6 misfire detected
P0307 - Cylinder 7 misfire detected
P0308 - Cylinder 8 misfire detected
P0313 - Misfire detected with low fuel
