What are the ignition timing marks for a 1996 Chevy camaro 5.7


Your vehicle has an electronic advancement inside the distributor. To properly set the ignition timing there is a plug that has to be separated. On the late 80s and early 90s it was on the firewall towards the passengers side. Brown or dark tan wire with a similar color plug. Follow the wiring harness from the distributor you can't miss it. If you leave this plug hooked up the engine will constantly try to adjust the timing and you will never get it set right. Once you get it set to 0° shut it off and hook the plug back up. The ecm will constantly adjust the timing sometimes up to 20° or more so that's y it looks off.

If a vehicle shuts off while driving down the road. then restarts after about 10 minutes, its a bad crank sensor or the wiring to the sensor. A check engine light may not turn on. If the light is on. You can take it to any auto parts store to have the code read by a scanner for free. Auto-zone, Advanced ETC. Its worth a try! But first check the fuel pump relay, It may be getting hot and shutting down pump. Try swapping a relay of the same type, if it is ok, thats the problem. Hope this helps!

1997 ford escort runs rough when cold starts but requires accerator gas pedal to be pressed down.Has over 251,00 miles on it,once it gets on the road runs great.What could the problem be?


Its just old and has high mileage but a tune up and replace with new spark plugs and spark plug wires would greatly help it run much better.

Asd 25a fuse blows every time i crank engine 2001 dodge grand caravan 3.3


Unplug these items,
- coil pack
- the multi wire connector on the back of the alternator
- both oxygen sensors

Install a new fuse and see if it blows when you turn the key on. If it does than there could be a problem with the fuel injectors or the wiring to the injectors or any of the items that where unplugged.

if it doesn't plug the coil pack back in and start the vehicle. If it blows with the coil pack plugged in replace the coil pack.

If it still doesn't blow with the coil pack plugged in and the engine running shut it down and plug in the alternator and start the vehicle. If it blos with the alternator plugged in replace the alternator.

Continue the same steps with the O2 sensors if needed.

If you have any questions let me know and I'll be happy to help. Thank you for using Fixya.com!

Sounds like its time for a tune up, new plug, wires, cap, rotor, fuel/air filter. Also have the timing checked. Could also be a fuel pump starting to go as well.

Vehicle runs rough and seems to be flooded


Assuming it has a 3.1 V-6, it could be any # of failures. Bad plug wires, ignition coils, control module (under coil packs), crankshaft position sensor, map sensor, throttle position sensor, egr valve, fuel pressure regulator, fuel injectors, engine coolant temperature sensor, vacuum leaks; have it scanned for trouble codes to help in diagnosing! If you think it is just over fueling (flooding),look at fuel pressure regulator or coolant temp sensor ( when they fail the computer thinks its always -40 F causing it to over fuel). A bad map sensor can cause the same. Hope this helps. Thanks in advance for rating me!
