Default 1995 saab 900 v6 hesitation problems

hey there i have a 1995 saab 900 v6 5 speed manual with 150k miles. recently just did a tune up. when acceleration away from junctions or up hills the car has begun to misfire/shudder and lose power. The misfire/shudder can last from a few seconds to a few minutes after which it clears and the car is OK. During the misfire pressing the accelerator simply causes an increase in misfire/shudder causing the car to slow down Leaving the accelerator at a fixed position allows the car to continue with the misfire/shudder until it eventually clears itself. The local garage has done a dignostic test and found no fault. Hope you can help with the matter. any one might know what the problem is?

I posted on this earlier this week and never really got any solutions to my problem. Seems to be a problem with the V6 900s.

My guess the problem is, Mass air flow sensor, spark plugs, spark plug wires,idle air control valve, Throttle position sensor, clogged cat im not sure thats all gueses i just took the parts off and cleaned them and got a better results but still hesitates in first gear feels like its runnin on 5 when theres 6 its only one cylinder that wont spark. sometimes it could be the spark plug gapping, i gapped at the saabs specs u can find them under the hood and it will tell you the specs. but still im not sure why my engine shakes like crazy im thinking its the MAF but i dont have alot of money to spend....TGI tax season hope this helps you guys or some where to start

Bad running on the V6 seems to be fairly often caused by a defective coil pak. While there are electrical tests that can be made, sometimes the coil pak may pass the tests but still be defective. You need to substitute a new or known good pack to be certain. A new pack may cost around $200. but you can could try a salvaged one from a junk yard. Try

A true tune up includes a great many things, one of which is the compression test.
Another is the condition of the engine mounts..An engine that is not well secured can be a problem.
Check the manuals for "tune up".

But in my case the hesitation problem only happens when the car warms up and does not do it all the time. Hesitation lasts for a couple of seconds then the car runs fine. Also I should mention that it will only happen if I turn the car off and start it up again. After the startup the hesitation happens when the car is warm and only for a couple of seconds.

My car has new plugs, wires MAF, o2 sensor timing belt and pullies etc. I had major service done last year.

None of thiis changes my opinion that the coil pak may be defective.
