Intermittent cold start misfires
Own a 99 civic ex (d16y8) work car. Sees mostly high way miles 4x a week. When the car sits for a couple days and can sometimes struggle to start and then when it finally fires bogs/breaks up real bad until it reaches operating temperature. During this, you can definitely smell gas, almost as if its flooded. One warm, it runs perfectly.
Ive noticed this can happen when sitting for a few days, but can also occasionally happens after I fill up with gasoline the next time I go to start it.
Any ideas? Plus/wires have roughly 35k on them. Car had 263k on it. Possibly a ignition coil, distributor cap in general? Fuel pump purges fine. Dirt MAF? PGM-FI failing? Curious if anyone else has had a similar problem and what they did to fixIT.
