Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Hello and thank you for your question,Is the check engine light coming on?
It would be very helpful if you could have the system scanned to see what the fault code and or codes are that are setting and in the mean time when was the last time you changed the fuel filter?
I would do the filter since you do not know when it was lasted changed and you should also have the fuel pressure checked after the replacement to make sure its with in specs. Give this a try and post back if that dose not resolve the problem and we can work from there. One other thing, most auto parts store such as Auto Zone will do a system scan for you at no charge. If the filter dose not resolve the lack of power then get the scan done and we can work from there.Please take a moment to rate my service so I can get credit for my time, the question remains open for follow up even after doing so, all you need to do is return to this question if need be.Thank you again.
