				Hi, I have a '94 Celica ST automatic, with about 170,000 miles. The check engine light is on and it's code 71. I already cleaned out the EGR, but the check engine light came back on after I reset it. So I got another EGR used from Pick a Part, and the light is back on again. Could it just be it needs a new sensor? 
			
			
					
		Also, smoke comes out of the tail pipe when I give it gas, and it smells really bad. Is it unrelated to the check engine light being on? I've considered having the engine rebuilt, but I want to make sure before I spend that much money. It has good compression. I bought valve seals but the person who was going to do them said it would be best to just rebuild the engine. And the person I bought the car from said he recently rebuilt the engine. So I just don't know.. I'd appreciate any ideas on these problems. Thank you!  |
