i have an 87 trans am with a 305 tpi. It has 140000 miles on it. i hadnt driven it for a while, two weeks or so, then i took it for an hour drive on the freeway. the service engine soon light was on the whole way. as soon as i saw it i pulled over and checked everything, oil, trans fulid, i turned the off and on a ffew times but the light stayed on. i kept an eye on temp and oil press the rest of the trip but they were fine the whoole way. the next day i was goin to take it to a mechanic buyt the light was off and stayed off the whole time. should i be worried? anything i should check?

 

probably egr... code 32. Its probably coked up and not flowing after allt he years of service. See the teck articles on how to retreve codes. I believe they have a section on obtaining the codes in there.

 

oh... i wouldnt even bother worrying if it is a 32... i dont even have mine and it works fine but you can get preignition knock from the increased combustion temps.

 

Scan for error codes.

 

yep scan for codes the ses lite has notihng to do with oil and temp
