Another thing to check would be the EGR valve. sometimes they would stick open or have a piece of carbon holding it open.

I would hold off on the EGR. A rough idle could be a stuck EGR but on throttle it would have little effect.

Thank for getting back to me. I thought that was the maf sensor. I cleaned everything in the whole area. I will check the egr valve tomorrow afternoon. Will post back as soon as I have any new info. As always thank you for your help. map and maf , I got confused. lol. gary r

If you are going to clean the MAF, use MAF sensor cleaner ONLY. Anything else will leave residue and cause the sensor data to be skewed.

Thanks for that info, I will pick some up before starting the work. gary r

Well thing,s were looking up. It was running smother, power was back. Well today while driving all of a sudden the motor viberated hard when leaving a stop. Feels like the trany is acting up. It,s hard to tell. no matter what gear I put it in ,the vibrations were still strong. It lugged on take off . From the looks I got a few times it must have sounded worse outside than inside. I feel there is a chance that I messed something up. Not sure what though. I did also find what I thought was to much slack in the gas pedal cable. At the throttle body there was 1/2 of deflection. Moving the pedal, there was a lot of cable moving before the gas was starting to increase. I hope this made sense . Thank,s in advance for any help you can offer. gary r

When it vibrated etc., did the engine RPMs increase or decrease?

, rpm would run higher, at a slow speed it would run around 2500. I would be going about 30 mph. I was going the speed limit. The vibration stayed with the car at all speeds.Thank you for getting back to me. gary r

When it vibrated etc. when leaving a stop, did the engine RPMs increase or decrease?

The rpm would increase to close to 2500 rpms till it shifted at that time their was a slight drop . . then they would climb back to 2500 range at 30 mph. thanks for helping me. gary r
