1999 Maxima Engine shaking

I know there were many people having this problem on Maxima's 4th generation. My Maxima engin is suddenly shaking bad. First, it only happened when I stopped at D or R shift, but now it happens while driving too. Since the Service Engine Soon SES is not lighted, so I could not find what trouble codes. Some people, who had this same problem, had taken to dealer but could not find the exact problem. Most cases were just guessing (ignition coil, spark plugs, MAF...). For instance, the example below. If ignition coil or MAF problem, then the SES should be lighted. Whoever acknowledge this problem and have it solved. I would appreciate for your advice.

I have a 1999 Nissan maxima with 60k. I took my car to Bert Ogden Nissan dealership in McAllen TX. because the "service engine soon" light came on and my car was not performing well. It drives smooth but every time it is in a complete stop or on park, the car would start to go FORWARD or SHAKE. They said that it needs all six engine coil, so I did pay $650.00. When I took it home, the car started to do the same think and then the light went on again. As of right now, it have been almost two weeks that they can not find the problem. They have replaced the harness and the computers but it is still the same. I'm very up sad and don't know what to do. If any one can help me out, I really appreciate your help and your info.

My 95 SE (purchased May 94) has a 5-speed, so I don't know if there are any potential problems related to auto trans (vacuum leak or electrical).

The only thing that has caused rough idle or power loss for me has been failed injectors (a common problem). I had 3 or 4 of them go out, one at a time over the years, and only once did the check engine light come on the same day (during a trip). The other times the light did not come on for several weeks to a month (maybe intermittant injector failure).

I did have the knock sensor replaced once, but that might have been a false positive at the time one of the injectors failed. The only other engine related electrical devices that ever failed were O2 sensors which did not affect how the engine ran. Never any problems with ignition.

It is still going strong and a joy to drive.

If problem is cylinder misfire:

- MAF affects via ECU; all cylinders behave 'equally' bad

- Coilpacks/Injectors may be disconnected and/or swapped = bad individual traced

- fuel pressure check with a pressure gauge

- ECU has the coil/injector driver circuits

- everythin is affected by pwr supply. Check voltage at ECU, all groundings, engine related connectors for oxidation; check/read

Disconnect alt charge wiresto test/troubleshoot for possible noise.
