Timing, Timing, and More $)(#&)(#&$_(%#_($* Timing

[BlackDynamite]

OK, so i've trying to figure out the sputter and i bought a reman distributor. Ok, so every time i've rebuilt a 7m, i never get the timing Dead on the first time, but enough playing with it,i eventually get it. Well, I got the new distributor in and noticed the mechanical timing was off a cog, so i adjusted it and had it in perfect time. I had the paper clip in the connector thingy and it was good. Idling perfect at 800 rpm, like a kitten. Then i started to drive and it got up to 3000 rpms, and it started to sputter/ back fire. I noticed the check engine light coming on and off every time it backfired. But, it would idle perfect after every time it did it. I'm guessing the engine was retarding the timing so i didn't blow up my engine, but wtf. Perfect timing = backfire? New Distributor, knock sensor, cap, wires, spark plugs, headgasket, head bolts, every damn thing. THis motor is breakin my balls. :1zhelp:

Edit-I do not have any codes, and this motor has upped compression from the machine work on head and block.

 

[BlackDynamite]

It also ran completely fine with the messed up distributor. I don't get it. I'm going down to the shop and redoing all the timing again and making sure of my work.

Also, I have an auto converted to manual. I run 93 Octane, and i'm running the wiring harness and ecu from the auto.

 

[BlackDynamite]

well i moved coggs, everything i could think off...but i still got the "launch control" like backfire

This is how it sounds....i'll try to get a video of it from my phone....

That sure sounds like a timing problem to me, or might have a problem with the distributor, new or rebuilt? Have you checked your firing order?

 

[BlackDynamite]

it was a rebuilt one from advanced auto. I can try to put in the old one and see what happens. The firing order should be A OK. I mean, would it idle perfectly with a plug wire wrong?

I had some weird codes. A code 22, and 43. also code 11 after I cleared codes. WHY THE HELL is my starter code coming up? It's new when i bought the car and has never failed me yet.

Though, the people before me could have not cleared the codes...it's possible


OH, it's running a little richer than before...maybe because of the retarding of t3h timing.

OH and THe EFI fuse popped. It happened while i was putting the paper clip in the diagnostic clip.

How is your engine oil level?
Is the knock sensor connection on tightly?

 

[BlackDynamite]

full, and it should be. I mean, it sudenly came loose when i put on the new distributor? i doubt it. i'll check though.

I'm gonna put on the old distributor on and see what happens.

Also, How can you find out top dead center, without using the mark on the crank pully?

The reason i ask, is that when we got the car, the pulley was loose. So i took it off and it had wore away at the crank pin(moonshaped unit that holds crank in place.)

Well, with some locktight and time, i got the pin straight. And i haven't removed the crank pully since. But it's on there tight and if it did move it would only be by 5 degrees or so.

 

[AJ'S 88NA]

Take out the #1 plug and put a pencil in the hole. Slowly turn the crank and watch the pencil until it stops going up, check your mark and it shoud be on the "O". The rotor should be pointing at #1 plug wire and the cam gears should be lined up on the marks. You'll have to check the rotor as you can have it 180 out.

 

[BlackDynamite]

Well, Now i have a few little kinks, but i did some tinkering today. Since i thought the crank pulley may be off, instead of putting it at 0, i moved it to 10 degree's as my TDC. Set the cams and it ran very similar to what i had before i changed the distributor. But every once in a while it will stutter around 3000 rpms, but it revs all the way up now. WHAT the hell is up with my motor. I can't get it Just right, but i was curious. Whenever you jump the terminals with the paper clip, what are you doing there? I mean, what if i were to change the timing, without the paper clip in?

I don't really understand how the crank pulley is off. Do you mean that the key was messed up and you have it just bolted on? I don't think that it will stay in place were it's suppose to be. The key way is what keeps it in place, the bolt holds it on. Check for TDC with the pencil. Then you will know how far off it is.

When you use a jumper wire you take out the timing adjustments the ECU will make so you can get an exact base timing without the ECU correcting it.

 

[BlackDynamite]

The key was messed up and damaged the grove it sat in. So i locktighted the key in the original place. It only messed it up SLightly enough to make the key not stay in place. But i don't know. I'm still having problems. I did the TDC thing with the pencil, but i wasn't sure. Is it RIGHT when the pencil stops moving?

 

[cuel]

You should check the code 22, and test accordingly(coolant temp sensor).

The 11 could be from popping the efi fuse. Reset the ecu again.

 

[BlackDynamite]

The coolant temp sensor had a split in the wire, which i fixed with electrical tape and a plastic piece. It has never throw that code until i messed with the wire that connects to the distributor, which connects to the wire that was split. Must have moved it wrong. Works fine and hasn't thrown the code since. I only get a code 11 after i rev the car up...then it will go back to the normal blinking. I'll reset for shits and giggles.

 

[BlackDynamite]

i reset and it didn't change. I'm going to put old distributor back in and see what happens. IF the old one works, what would cause the new one to do that? I mean, if there was a short in the wire, it would run like dog poop or cut off. I'll fill yah in.

 

[Spade]

Dam man you going through the EXACT same thing im going through! Crank key and everything except im running a turbo head. Wow what a stroke of luck someone with my exact same problem. Try checking your tps for spec. then try adjusting it. if it is not in spec and you can not git it in spec it probally need to be replaced. Also for shi*s and giggles check you maf to. I adjusted my tps and the stutter went to a different rpm. mines at 4000 untill i adjust my tps then it moves around from 3300 to 5600 rpm. I chould be wrong but its worth a try. let me know how it goes. :runaway:

 

[BlackDynamite]

well, i took the new distributor off and put old one back in EXACT same place and set 10 Degrees as my TDC. Revs and runs fine.

W T F F F F F

I guess the old one was ok.... :wtf:


Timing was set a little past 15 Degrees. But remember my TDC is at 10, not 0.

I put screw driver in and it started to go down at 0

If your TDC is at +10 degrees then stock timing should be set at +20 on yours, might be a guess, the gauge only shows +15.

 

[BlackDynamite]

yes it's about 20, spaced out about the same. Runs like it did before. THanks for the help guys, even though i don't have a new distributor...it gets me my money back and a vehicle to work, so i can go 1jz ;]

 

[Spade]

congrads man. good work. ill check mine timing again. mabe mine is the same.
