hi, the other day i was driving home from eating dinner and all of a sudden my auto 96 saturn sl2 starts to shake and i noticed that when it got ready to shift into 3rd it couldn't and starting shaking worse when it couldn't shift. and i got a serivice engine light and then i turned off the street because it was a bust street i was on and it could not keep an idle i surged between 1100 rpm and 300 until it stalled and then i started it up and it is fine it was a little hard to start like it wanted to start but couldn't but then like 1 second later it started up and has been fine since.so i got the codes read. and i got this. p1106d, map sensor circuit,, and p1406a egr pintle position sensor circuit. and i am wondering also if there is a tba about it because i was reading about one that the 95 and 96 saturns have with the fuel ingectors grounded because of wire chaffing. and also what would need to be the problem with those codes.

I'm no expert, but in my S series experience, I would clean out that EGR valve. It is probably pretty carboned up causing the pintel to stick and not move freely. I had a similar problem with my '95 SL-2. It was an intermitent problem. A mechanic friend of mine suggested cleaning the EGR. After doing so, the shaking, "missing" and stalling never returned.

Mine did the same exact thing. And on any given day, barely pressing down the accelerator, it would jump to 3000 RPM out of nowhere. But I got the code read and all it told me was cylinder four was mifiring.

ok i will try that and do u know if that is what caused the map sensor one?

No I don't know...sorry
