2 Problems! Temp. Gauge, Engine Light
I have 2 problems i been working on for a while on a 97 f-150 with 5.4 engine. First, my temperature gauge pegs out into hot after the engine is running about 2 minutes.....some tell me this is the gauge itself and the only solution is a whole new cluster. Second, my check engine ligh is on. Just had plugs changed, new egr valve, and o2 sensor changed. The code reader says there is a low reading on the o2 sensor but i changed it twice and no difference. I also found out the manufactor code says i have a vacuum line on the egr valve that is clogged or unplugged but i checked that and is fine..... please help!
