I have a 1993 Honda Accord Wagon. Everytime I go to start it after it’s not been run for even as little as 15 minutes it fires and starts to run but takes it at least 20-30 seconds tops of messing with the gas pedal before it will stay running and once it is running it won’t get any real power until you hit the gas to 2k rpm and it’ll pop and run enough to move the car. It also is running rough and sometimes makes a pop noise and acts like it slightly misfires on one cylinder. When driven it doesn’t have any power until about 25 mph and you have to floor the gas for it to really get going after first putting it in drive. No check engine lIght is on. IN NEED OF DESPERATE HELP.
