Engine Performance problem
1987 Honda CRX 4 cyl Front Wheel Drive Manual 108542 miles
hi I own a 1987 honda CRX-si. I put a K&N cold air kit on it and it ran awesome. It got like 41 mpg. Then I decided to put some plugs and wires on it. Long story short a spark plug got cross threaded in it and I ended up taking the head off it and having it milled and the hole re-tapped. I put it all back together along with a header ( and same o2 sensor). It started right up and runs great. But it sometimes studders going 50 in top gear but smoothes out at 55. Then sometimes the PGM-FI (programmed feul injection) light comes on (when it studders). The PGM-FI light stays on until I shut the car off. I am guessing this has something to do with my bad gas mileage which has dropped to about 24 mpg. Why is my gas mileage so bad?
have the same problem?
