Here's a breakdown of likely problems and what to do:
* Improper Air/Fuel Mixture: The new intake likely changes the amount of air entering the engine. If the engine's computer (PCM) isn't compensating by adjusting fuel delivery, you'll get a lean mixture (too much air, not enough fuel). This leads to backfires, loss of power, and the check engine light.
* Mass Airflow Sensor (MAF) Issues: The MAF sensor measures the amount of air entering the engine. A poorly installed intake or one incompatible with the existing MAF sensor can give inaccurate readings, leading to incorrect fuel delivery.
* Vacuum Leaks: The intake system needs to be properly sealed. A leak can disrupt the airflow, causing poor performance and the check engine light.
* Incorrect Intake for the Engine: It's possible the garage installed an intake designed for a different engine or a different year/model S10 Blazer.
* Throttle Position Sensor (TPS) Problems: While less likely, an improperly positioned intake could affect the TPS, leading to similar problems.
What you should do:
1. Return to the Garage: The first and most important step is to go back to the garage that installed the intake. They are responsible for ensuring the installation and any necessary tuning is correct. This is especially crucial if you paid for the work. Explain all the symptoms clearly.
2. Get a Diagnostic Scan: If the garage refuses to help or isn't able to solve the problem, take your S10 Blazer to a reputable mechanic or auto parts store that can perform a diagnostic scan. The scan will reveal the specific trouble codes stored in your vehicle's computer, providing clues about the exact cause of the issues.
3. Check for Obvious Problems (If you're mechanically inclined): Carefully inspect the intake installation. Look for loose connections, vacuum leaks, and anything that appears out of place. However, don't attempt any repairs yourself unless you are experienced with automotive repair.
Important Note: Driving the vehicle in this condition can cause further damage to the engine. Limit driving to short trips until the issue is resolved.
