A few days ago my check engine light came up on my 98' Honda Accord. I did notice since becoming hot outside that my car was operating differently. It jerks when i accelerate and it doesn't accerlate as fast. It's now at 160,000 miles. The problem code 1259 came up when I had it checked at Autozone. It may help to know that I had an oilchange today (3days after the light came on). Now the maint. required light has turned on as well. I do know that it is a 4cyl. and also it is a VTEC.
I was wondering what it might be and if it may be something costly. Is this something I could easily fix??
