83 Chevy van 30 miss fires on takeoff and at speed timing was set them very hard to start reset them pinging started still missfired at speed?

seems that the timing is still incorrect. the distributor may be worn and causing this.problem may also be the points, a crack in the distributer cap,

Why wont your Renault kangoo start you just changed the timing belt?
If it started previouslt then something disconnected (sensor etc) or timing is wrong
What is the correct timing for the MSD Ignition System on a Jeep J10 360 4bbl?
There is no definite answer to that. The book will probably say 10* BTDC but I get the best performance and no pinging at 15-16*. I think the book is usually pretty conservative. This sounds old school, but you will get the best results by timing it to best idle, then backing it off a hair at a time if it starts hard.
1988 Lincoln Mark 7 LSC when you accelerate hard the car does not take off fast and it starts clicking you have to gradually accelerate it so there won't be any clicking What could it be?
I would check the timing (sounds like the car is pinging) first put some premium gas in it if that doesn't work then check the timing! What I did on my car was power time it, while someone is holding the brake real tight rev up the eng to about 2000 RPM then slowly turn the distributer till you hear the pinging then turn it back slightly till it stops and you will have the total amount of timing you can run! If you use regular gas the car will not peform good from a stop on acceleration! These cars have to run on premium gas if you have the 5.0 HO engine (Mustang GT Engine) they put this eng. in all Mark vii's 1988 and up! If this doesn't work then you have another problem???????
What is wrong if your 90 Mercury 5.0 started up fine and you turned the idle up but when you whet to drive it had no power and lots of popping from the exhaust when you put it in neutral?
The popping from the exhaust and the lack of power sounds like there is something in the timing. Most likely the timing chain is worn and needs replacing.
Can a bad knock sensor cause the car do start bad?
A knock sensor assures that you're getting as much power and fuel economy as is possible from your engine. More details: A knock sensor allows the engine to run with the ignition timing as far advanced as possible. The computer will continue to advance the timing until the knock sensor detects pinging. At that point the computer retards the ignition timing just enough for the pinging to stop. The knock sensor responds to spark knock caused by Pre-detonation of the Air/Fuel mixture. As the flame front moves out from the spark plug ignition point, pressure waves in the chamber crash into the piston or cylinder walls resulting in a sound known as a knock or ping. This is caused by using a fuel with a low octane rating, overheating, or over advanced timing. Sometimes it can be caused by hot carbon deposits on the piston or cylinder head that raise compression. A knock sensor is comprised of Piezoelectric materials; Crystals that when impacted, generate a voltage (same idea as a BBQ ignitor). This voltage is monitored by the computer, and when an irregularity is detected, the computer corrects timing in VVT (variable valve timing) engines, or triggers a DTC Diagnostic Trouble Code) in older vehicles.
What are the benefits of running advanced timing or retarded timing?
You will get pinging if you advance it and you will loose gas mileage and power if you slow it.
Is a rapid constant pinging or knocking in engine due to egr problem or what other possibilities?
Check the engine timing first. Pinging or knocking,especially under acceleration could be early detenation caused by advanced timing.
What would cause a pinging sound in the 2.3L engine in a 95 ranger The timing belt was just replaced Could it not be set right The truck feels like it has less power than it did before the belt was r?
Sounds like the timing is off just a bit ur getting the start of detonation which makes the pinging noise ur hearing. That is the most logical (as or if ) it was not pinging before the timing belt was replaced.
Where to set timing on 1970 350 300 hp?
Try 8 degrees BTDC and listen for part-throttle pinging. More is better up until the point where you notice pinging.
Where should you set the timing on a 1985 Chevy 2.8 v6 with a aftermarket webber carb and no emissions?
Advance the distributor until you hear pinging under a load, then back off until the pinging stops.
What pressure ratio causes knocking in a petrol engine?
The pressure ratio does not cause pinging in an internal combustion engine. Pinging is the result of the air/fuel mixture igniying before the piston is in the propper position. Chep gas will cause pinging because it is igniting too quickly. Too high a compression ratio will do the same thing. Ingnition timing that is too far advanced will do the same thing. Back off your ignition timing two degrees at a time until the pinging stops, or buy a higher octane fuel.
Can a bad knock sensor be responsible for rough shifting?
No, the knock sensor only retards the timing when it detects the engine pinging.
Why is your f 150 still pinging after tuning and adding high octane fuel?
could be the timing is off or your valves need adjusting
What is the function of a antiknock sensor on a 1995 Acura Legend?
The sensor senses when the engine is pinging or called spark knock. It then sends a signal to the engine control module. The engine control module then temporarily retards the timing until the pinging stops.
Chevy 350 pinging under load?
If it's carburated, you might be able to back off the timing a little. If it's computer controlled, there could be a sensor gone bad somewhere. Sometimes you can put in a higher octane fuel to eliminate pinging.
How do you fix pinging on a 1989 Volvo 240 despite running it on high octane fuel?
Adjust ignition timing. check knock sensor.
How do you know if your car timing is off?
it could have a rough idle, knocking or pinging, sputtering, smell strong like gas, etc. careful when you line up timing, it's best to only have to do it once.
