Its me again. I just had my rack and pinion(2008 pontiac grand prix) replaced with plenty of problems in between. I got it back 2 days ago. Yesterday I drove it for over 70 miles with no issues. This morning, Im driving on the highway and my HUD shows "reduced engine power" message. Now the shop I go to,at least with me, has a habit of causing my car to have problems it never had prior. Last summer I needed my head rebuilt and radiator replaced. 2 days after that my car stalled at a light by my house. Had the shop look at it and he said that there was corrosion somewhere and fixed it for free. the next day my CEL came on and again I brought it back to the shop. This time he scanned the codes and said I needed a new crankshaft sensor and a new upstream O2 sensor. Got both replaced. CEL never went off. Now its March and this message comes up. He said to bring it back today. Do you guys think it could be something he did while fixing my rack and pinion or do you think this is unrelated? I paid $1200 for the rack and pinion last week. Cant afford any more issues with this car. I bought it in 2016 with 130k on it. Paid $4700 cash. In the last 3 years I've put over $5k back into it.Currently has 190k on it.
