Hi,

All gasoline fed engines only needs two (2) factors to start/run, spark and fuel.Check for the presence of both.

  • remove one of the sparkplugs, reconnect it to its wire and place on top of any metal part of the engine, crank, there should be spark;
  • remove the cover of the air filter/cleaner, pour raw fuel, start;
  • high idle could be caused by vacuum leak.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

You may need check the spark plug. Cleaning or Replacing it could possibly fix the issue. Also clean or replace the battery terminals. Testing a different battery is another option to try.

Idle rpm too high


You don't say if the engine is carb or fuel injected.
If it has a carb, it could be sticking linkage for the fast idle to the choke.
If it is fuel injected it could be a faulty idle air control valve.
Or it could be something holding the throttle open like a binding cable.

I have 1990 ford f150 5.8 liter it idles high when in park and idles about 1200 rpm when in gear and sometimes surges up and down. i have clean the idle control and check showing 12.5 ohms still won&#


One common problem is a vac leak or a sticking throttle plate.
The computer controls idle speed by how much air is allowed into the intake. The idle control valve could be sticking even tho you have cleaned it, or have a faulty motor.

I have a 1984 ford f150. The truck idles very high when in park but when you put in drive or reverse it goes down to normal. It has duel straight exhaust on it and I wonder if that could be the prob. Idk.


you didnt say if it was happening only during the initial warm up of the vehicle or all the time. if it is just during warm up this is not too unusual as long as the engine isnt racing. if it is just a "high idle", say arround 2,000 rpm's its normal. the idle would usually go down as the vehicle reaches operating temperature. when you put the vehicle in gear, you are actually loading the engine slightly, thats why the idle comes down then. when in park the engine has no load on it so it is free to rev a little higher at these times. if it a at a high idle constantly, then i would start looking for sticking throttle cable, binding throttle plates, ect and remedy the problem. this should not have anything to do with the dual exhaust.

Got a 85 ford f150 has a 302 holly carb. was running fine ran low on gas and now cuts out wont back out of drive way idles fine but hit the gas and it stalls


strip and clean out the carb,or quick fix ,rev engine with air filter off and then hold hand over intake this may or may not not cure it .because when hand is held over carb and stops air the suction will draw any muck through the jets

Check your throttle body, for the throttle plate sticking.  Also check for a vacuum leak.
