    there is a fuel pressure test port on the top of the engine in the fuel supply line to the injectors, it is like a tire valve but metal, u will need to buy a fuel pressure test guage to access this port, about $20 at any Kragen or Autozone parts store, do u have a EFI V8?

Honda accord 1997 my car is having trouble idling it was over heating it had a hole in the radatior and i got that fixed and now it is having trouble staying started its puttering all the way threw first...


Sadly, it sounds like the overheating caused the cylinder head to warp. If this is the case, the head needs to be pulled out and resurfaced. Many times, when the head warps, it will contaminate the cooling water.... look for traces of oil in the coolant. Other times, you will be able to see a white cloud, water vapor, coming out of the exhaust. One remote possibility is that when the radiator was fixed, a sensor was disconnected, and if this was the case, the check engine light should be on.

Try cleaning the throttle body (throttle body cleanner ONLY). Uncover the TB (engine off) & inspect the butterfly by moving the throttle by hand, if the underside & down inside the TB has a bunch of carbon (black soot) that could hamper with the idle! Also, check the fuel pressure @ the rail, under 60 psi could cause bad idle. Air filter clean? Did you make SURE that the terminals under the spider injector wiring harness has NO pins bent over during connection?! Also could check the throttle possition sensor & the mass air flow sensor if need be.

My gas tank was running below E the other day. i made it to the gas station and filled up and my car started to "putter" at the first red light i came to. It drove but took a second to pick up full speed...


What happens when you let the fuel tank run empty or nearly empty is any trash and or water that has accumulated at the bottom has become stirred when refueled. If the car still "putters", I suggest replacing the fuel filter and see if that clears the problem. I also recommend that you also run a small bottle of Lucas fuel conditioner or fuel injector cleaner to help loosen and remove any trash built up in the fuel injectors.
