Understand this code is everywhere when you google and I've read all the threads, just curious if it's ok or the tune is running a bit lean.


Car has the p0300 code then I thought the plugs may of been fouled so new NGk iridium plugs 1 step colder. Same code, decided to switch coil 1 and 2 and now p0302 which then I switched 2 and 4, still shows p0302. Clear the code, drove a few miles with no cel, this morning on cold start.. Again p0300 appears. Even with the code.. The car starts fine and drives fine and idle seems to be at 650-700 with no horrible misfire shakes..

Also I did cleans the Maf and checked for all vaccum leak.


Vortech s.c
Test pipes
Rc 440
Ultech

 

CEL comes on intermittenly, cold start with cel then drove it for a while. Notice its not there anymore, is this fine to keep driving?

 

may have vacuum leak somewhere

 

Update - Driving the car all day today and code now shows p0300, p0132, and p0152(cats gone). I figured that it all make sense now, replaced new 02, cleared code driving normally. Now have pending code - P0302 lol, will be switching over injectors tommorrow to see if misfire follows oh and compression for sure.

-I've tried spraying carb around lines and idle seems to stay the same (could be leaking on bottom where i didnt get the carb to though)

-Also idle does look pretty low I'd say 450-520, but car does not stall or shut off or shake to notice.(Did the TB reset pedal procedure with same results. Wish me luck on compression tommorrow... hopefully not a bad valve.


-Anyone know what the fuel pressure should be at? Mines current at 43 on idle... Thanks

 

I also have the code. Haven't run tests. Car randomly stalls

 

- Faulty spark plug 2
- Faulty ignition coil 2

The coil stem plastic may have cracks on the inside causing the charge to arc to the head. Thus resulting in the code.
