SOURCE: runs terrible, p1391 is the

since you've replaced all the expensive components 1st.i suggest you look towards clogged fuel injectors next.try some sea foam,add it to your fuel tank to clean the fuel injectors.your computer tells the injectors and the crank sensor tells them when to pulse. you may only have partially clogged fuel injectors or water in the fuel.the seafoam will dry up any moisture in your fuel tank and also unclog fuel injectors. lucas fuel injector cleaner is what i usually recommend,but your issue call for extreme cleaning. try the seafoam,it costs $7.99 per bottle and treats 25 gallons of fuel.follow the instructions on the bottle.but if you suspect alot of water in the fuel tank,i suggest clear rubbing alcohol !/2 bottle to your fuel tank directly.it will not hurt the engine,but will remove excess water from the gas tank. thank you,for choosing fixya.com!

The distributor gear. It wears down and causes rough idling to no start. Pull the distributor, look where the rotor button is pointing as it needs to go in the exact same position. you can get just the gear and replace it. it is held in by a drive pin. Push it out and swap gears and reuse the drive pin. hammer it in.

1995 nissan hardbody, replaced timing chain with new kit. Crank, cam sprockets woodruff keys at12 o'clock. Punch marks aligned with black timing chain links. Engine timed at 10 degree BTDC. -5, tdc, 5, 10,...


It starts up easy and idles good? And timing is at 10 BTDC? Sounds like you got it right then. I would check the fuel pressure at the fuel rail first. If fuel pressure is correct, maybe the throttle position sensor is bad?

Do you have vacuum advance on the distributor, or is it controlled by the ecu? If a vacuum advance device, maybe that is the problem. Beyond that, I don't know.

Need tune specs on '89 5.7 GMC


Spark plugs are set at 0.035 inch.
Ignition timing is set at 0 degrees BTDC. The computer then controls the timing from there. There will be a wire that you unplug before you set the timing, then once you have verified that the timing is at 0 degrees, then reconnect the wire and you're done.

I need to know the timing for my 350


Not sure if the 95 is the same as the 93. On the '93 there is a timing advance wire you have to unplug (brown wire near the distributor on the firewall with a plug connector.) Start it up with the wire unplugged and set timing to 0 degrees BTDC. Turn off engine. Plug wire back in and computer takes over. There should be a sticker on the radiator shroud that gives timing and spark gap settings.

My 88 Mustang GT boggs on me.


Sounds like the timing is off. When looking at the distributor cap right next to it should be 2 wires with a plug at the end of it. Unplug it and start the car then check your timing . Make sure you mark the crank 10 degrees BTDC. You can bump it to 14 degrees BTDC if you like to gain 10 extra hp. After timing is set turn off car plug spout back in to the 2 wire outlet.(You have to unplug the 2wires in order to time a 5.0 the 2 wires control vaccum)

Nissan navara 1986 2.4L petrol timing problem


For timing, on 1981 and later 4 cyl engines (from the Haynes manual):
1. Turn camshaft so both valves for #1 cylinder are closed, and turn the crankshaft so #1 piston is at top dead center (woodruff key should be pointing up).
2. Engage the camshaft sprocket (with stamped numbers facing out) into the timing chain, and install the chain around the crankshaft sprocket. The bright links on the chain should be aligned with the timing mark on the crankshaft sprocket (on the right side as you look at it) and with the number "2" stamped into the camshaft sprocket, which should also be on the right side as you look at it.
3. Install the camshaft sprocket onto the camshaft, aligning the camshaft dowel pin with the number "2" hole near the center of the sprocket.

For the firing order and wiring routing for the 8 plug 4 cylinder engine: (Plugs on the intake manifold side are coded "I", and on the exhaust manifold side are coded "E")

Wire to 1I should be connected to tower on the distributor facing directly to the front of the vehicle. Going counterclockwise from there, the order is (1I), 2E, 3I, 1E, 4I, 3E, 2I, and 4E.
