I just did a JDM B16A swap in my 89 Civic sedan and ran into a problem. Here goes - When I drive around all day the engine runs fine but when I drive home from town on the highway at about 60mph the engine lags, and during the lag when I press the gas pedal nothing happens all it does is open the throttle and I can hear it but it the engine will not rev any higher. Now when I put it in neutral (still on the highway rolling at about 50mph) the engine shuts off. I then pull on the side of the highway and try to start it but it wont start. But when I wait a minute or so and try again it starts up and I drive off for about 10-15 minutes and it starts doing it again, and this keeps happening over and over. But here’s the funny thing, sometimes when the engine lags, I keep pressing the gas pedal and sometimes the engine kicks in and I can drive off till the next engine lag. What the heck is wrong? PLEASE ANYONE HELP!!!!!!!!!!!!
