Seeking advice as I haven't been able to find a solution here or on google to the specific problem I've been experiencing.
SYMPTOMS
- Starting issues: When the engine is cold the car cranks strong but does not catch immediately. It may take 5 seconds and once started the revs will drop at first then will rise to choke. If the engine is started again within 15 to 20 minutes, it will start with ease sometimes immediately or 'as new'
HISTORY
- I have an EM1 150000kms with no mods. I made the fatal mistake of washing the engine. Eventually, after 30-40kms the car began sputtering, I lost a lot of power until the engine died and I had to get it towed to Hanny's.
- Rob replaced the dizzy and the car still would not start. He then pulled out all spark plugs and noticed water in there. He then blasted all the water out and replaced the spark plugs. Car started fine but was still sputtering.
- Went back to Rob on the same day and got my injectors cleaned. Car still sputtering.
- One week later: Car started and ran like normal.
- Then a rattling noise in my exhaust got louder. The cat melted and blocked approx 80% of the airflow. (Car running rich).
- Replaced the cat. Car running like normal and power restored however still having starting issues.
- Battery eventually died and had that replaced.
- LAST WEEK: I did a minor service + replaced spark plugs, reset ECU. Problem still exists.
- TODAY: Strong crank but still won't start immediately. Though I haven't been able to check it also seems like my fuel efficiency has dropped.
- No Engine Lights come on
SUSPICIONS
- Ignition Timing Issues
- O2 sensor damaged when cat melted
- Low pressure in fuel line
Would appreciate any advice or assistance. As I can't figure out what the problems is. My next course of action was to replace the O2 sensor and hope for the best.
I look forward to any advice or suggestions.
