4.6 questions again

[jp67stang]

alright thing is running, seems to be running great, seems slow to rev up. but i havent ran it that much. at the same time it did back fire on me too only twice when i gave it gas idk if thats from bad plugs or not yet or one of the codes that the computer is showing. anyways question is how can i tell if i didnt get the timeing chain right on the 4.6. would it be noticable if i did or what. any help would be great, also i did hear a clunck from it one time no idea if it was anything or not. so if the valve did hit the piston it would more then likely be doin it the whole time right. sorry know this is not formatted the best dont but just looking for answers from people before its to late and something big happens.

[jp67stang]

any one any help

so if the valve did hit the piston it would more then likely be doin it the whole time right.

not necessarily, if you floated a valve, that wouldn't be the case... I remember taking off the heads on a 2v 4.6 to do a PI swap once and finding out a valve had hit a piston once... the owner had ran it until the day before we tore into it, not even knowing he'd done that.

For the slow to rev up stuff, check for vacuum leaks. Not sure what the clunk would be or how you'd be able to tell whether the timing is right or not though, I was too many beers into the pi swap at that point to remember the timing chain part

i c thanks ill look for some vac leaks and ya idk when i first start it and try to hit the gas it dies. then if i let it warm up i can rev it up and it only back fired 2 times when i was running it removed spark plugs and got new ones few looked a little heated up at one point so it could just be from that ill see tomorrow

Does it idle good or does it act like it has a miss?

[gutlas5]

nothings missing, it's all there. thats why it runs, duh

seems to idle great i just drove it to the gas station and new gas was 100 percent inprovement still doesnt seem rightbut its not poping any code either. i ran it for awile and its been sitting all after noon ill see how its running in a little wile. might have just been the bad gas.

[jp67stang]

no it seems to have a miss and now its back fireing a little think its the plug wires because thats what i was messing with and it was starting to run worse.

[gutlas5]

when ever i do a motor swap of sorts like a used engine (i think thats what u put in?) i always do little things to prevent hick-ups, like plugs wires, t stat, hoses, shit liek that

What did the codes say?

[jp67stang]

What did the codes say?

p0118 and po125 it has to do with temp sensors its becase i have yet to tap the otherside for the temp sensor think that might be what it is. because on of the codes had to do with close loop fuel had to do with temp sensor

How do the plugs look. Does it smell rich?

[wiplash]

Holy fuck dude, you need your OWN tech section! Good luck with it though!

[jp67stang]

How do the plugs look. Does it smell rich?

depends its little rich smelling when i plug in the connector but thats because its telling the car its cold so it puts it on the warm up cycle. then it seems fine when i disconnect it but the fan is on all the time im thinkin i just have to drill and tap this hole it may be what all my problems are from .
the plugs idk they were the plug that were in the heads i switched them out now.
