what is the problem if my spark plugs have a kind of orange glaze on one side of them
-
kind of pink i guess
-
When was the last tune up. Do you us any aditives in your gas.
-
its been a little while but not that long and i dont drive it daily. and no ive not poured anything in it since these plugs. been having small problem. feels like a missfire. soo just checking to see.
-
It may be running lean.I have never seen orangeish or pinkish color on plugs.
-
Did you just put the carb on or do any other changes.
-
post pix. Are all of them the same?
-
The real help has arived. VILE!!
-
well i pulled the front one out of each side. and they were the same didnt pull the others out. And no i havent made any changes. i just put a new trans in and every since then it hasnt ran right
-
when you put the new trans in did you tilt the engine unsupported? Maybe the distributor cap hit the firewall (crack)? did you knock a vacuum hose off?
-
ive pulled the cap and everything everything looks legit. but at idle it has a small shake not real noticeable. but going down the road if i punch it under load it misses and sometimes backfires
-
and it's ever since you replaced your trans? Double check your cap and your connections/wires
-
i dont that. pulled each one checked em. pulled the cap checked for cracks cleaned it out. checked rotor. im starting to think it might be my carburetor but dont know a lot about this edelbroc
-
honestly it sounds like a vacuum leak. you should try spraying starting fluid (or something similar) around the base of the intake...see if the idle changes. i'd bet it's a blown intake gasket...maybe around the back of the motor...i'd spray on the intake as well, to make sure there's no hairline cracks that you can't see with the naked eye...
-
ok ill check it out. now that you say something when i was washing the motor i noticed it change tone.
-
wd 40 wont eat up anything will it?
-
also it has hard time starting when cold and runs real rough at first
-
Did you check for vacuum leaks? Cup your hand over the top of the carb as to restrict the air flow and see what happens.... Don't block it off totally (good way to break a ring)
-
I covered it as much as possible and still didnt die. should i be able to squeese the vaccum line for the transmission?
-
man, the SAME thing happened with my '88 Mustang GT. i was baffled as to why the idle was really high/erratic and it ran like crap...i had tried most everything, couldn't find a vac. leak...one day i was screwin around and decided to cover the TB to kill it...it sucked in the cardboard (just grabbed a piece to cover the TB) tight to it and KEPT RUNNING! i cracked up. then i went and got intake gaskets and all was well after that...
-
hmm. i covered it with both my hands as much as i could it started to stumble but didnt die. but i cant find any leaks around the intake.
-
well, if you covered the carb and it still had enough air to keep running, where do you think it's getting it from? lol, there IS a leak, and a pretty good one if it's enough to keep it running. it is most likely at the end of the intake where you can't really spray...you need intake gaskets...
-
Mist down your wires/distributor cap with some water and see if it runs worse.
