hello
I recently bought a 1999 Saab 9-3 with 300 000km on it.
The car drove fine for the first 100 kilometers or so, then when i went to germany to test it out at full speed, this is what happened:
after driving 212 km indicated on gps, that is, the max speed reached... sustained for about one minute, then driven at about 145km/h... after 20 minutes the RPM started jumping on its own up and down, you could feel slight jumps when driving, simmilar to as when gears are not changed smoothly.
then after moving to slower speeds once out of highway, the RPM went way high. On idle it jumps to max by itself. happens all the time since then. It is only controllable with careful combination of brake and clutch pushing.
if you put higher gears at slow speeds, it is controllable better. driving is very tricky, check engine is flashing all the time (at first it didnt lit up straight away, now each time the key is put in, but ignition not started yet,
the checking reports OK on SID but check engine yellow indicator on dashboard flashes (it is almost in the SOS morse code rythm
), and well - the car is barely drivable.
manual says it is either something to do with fuel injection system or something else, cant remember.
after reading forums i assume it is the fuel pump, but most people lose power. i have the opposite, like the car wanted to launch into space..
I checked the gas pedal lever and it is working fine.
Could it be some simple thing like a sensor or something? I first thought it had something to do with cruise control, but it matters little, if at all, when turned on.
So can i be sure whether it is the fuel pump so that i can purchase it?
I plan to ask the salesman to spare me the maintenance costs as it is something that happened immediately after purchase, still would buy the pump myself...
or maybe it is something stupid and simple? how can i be sure? what do you guys think?
