[84YotaBoy]

I got a new truck don't know much of it but it wont rev past 3500 and it is slow revving getting there and sounds bad any help is appreciated....ive just put in new timing chain adjusted valves new distributer cap and rotor motor doesn't sound like it has anything wrong internally.

Remove the 02 sensor and go drive it and see if its better. If it is your catalytic converter is plugging up.

Or the timing is off when it was put together...How'd it run before the work?

Timing chain could be off by 1 tooth. It happened with my old truck and it ran like **** until it was fixed.

Ya this too....:awesomework:

 

[84YotaBoy]

thanks the timing is correct didn't really rev it before since I knew the chain was bad how does the chain get off by one tooth

 

[84YotaBoy]

is there a way to adjust it without taking it all apart again
also after 3500 it starts to back fire

 

[zukkev]

backfire through the intake or exhaust?

 

[zukkev]

Pull the valve cover, rotate the crank to TDC #1 compression, and check the dot on the cam pulley...should be slightly left of straight up 12 oclock position looking at it from the front...

its backfiring thru the exhaust and ill check that tomorrow when I did timing chain I made sure I kept the sprockets in the proper place could it have anything to do with my intake sensor

 

[--toyguy---]

probably bad ECU

When you say backfire do you mean the neighbors might thing you are shooting a gun or just a strong miss?

I had an 87 that was acting similar and it was a combination of a vacuum leak and a messed up intake gasket letting in unregulated air.

If the cat isn't clogged, there may be a crack in the ignition coil. The one on my Jeep just about drove me crazy(er) recently.

 

[84YotaBoy]

the backfiring sounds like a miss not like a gun shot I don't have a cat on it its 2.5 exhaust to a flowmaster it has good flow also

 

[Jacob]

Was it doing this before you did the timing chain and other stuff?

 

[zukkev]

When you say backfire, is it more like a popping sound thru the intake or exhaust? Did you properly adjust the valves?

 

[WHITE TRASH1]

Sounds like the timing is seriously retarded. I'd start with cam timing and valve adjustment and check initial ignition timing while you're in the neighborhood.
