I have a two and it's intermittent but when I'm driving down the road the lights on my Dash start blinking if I put it in idle then they stop blinking when I put it back in gear they start blinking and the blinking gets harder as I accelerate

SOURCE: 2001 Saab 9-3 was driving

take the vehicle to your nearest saab dealer and ask for a diagnostic scan, yuo have a sensor failure, if left it could be expensive.

Oil pressure might actually be a bit high for idle. High or low oil pressure in an older engine tends to be indicative of some serious issues. Oil pressure that is too high tends to be a clue that you have serious carbon build up. That aside, have you tried running a higher octane fuel, or perhaps adding an octane booster to your normal grade? Pinging can become knocking in a badly worn engine. One recommendation: At your next oil change try substituting a quart of marvel mystery oil or lucas engine oil treatment in place of one quart of your normal oil. Both have some pretty good track records for helping to free up sticking valves and break up carbon in older engines. I'm an old timer myself, and I personally swear by Marvel for older engines. There is no "rebuild in a can" but Marvel comes close. Give those a shot, let me know what happens.

SOURCE: 1999 Ford Windstar, idles rough, slow acceleration

sounds like a large vacuum hose was knocked off the engine when they pulled the trans out, have that checked.

SOURCE: Hyundai i30 Diesel automatic won't accelerate above idle at light

DOES THE ENGINE MIL WARNING LIGHT COME ON? WITH OUT MORE INFO YOU NEED TO CHECK MOTOR ON A CODE READER FOR STORED FAULTS, CHECK ALL AIR LINES TO EMMISION CONTROL, , SOUNDS LIKE YOU HAVE GONE INTO SAFE MODE, A SPLIT OR LEAKING PIPE ON THE INTERCOOLER IS A COMON FAULT ON THESE, IF YOU SWITCH ENGINE OF AND BACK ON QUICKLY WITH MOTOR RUNNING WITH OUT STALLING MOTOR AND IT CLEARS THEN IT IS PROBERLY THE SAFE MODE CUTING IN MEANING A FAULT HAS BEEN SEEN BY PCM

Testimonial: "Thanks.Didn't notice any engine lights came on. I had a problem free day today, but if it happens again will check warnings and PCM computer check"

SOURCE: My check engine light is on and it often shakes

Bring it in so that the check engine light will be off and it will run smoother.
