Car not running right after tune-up?

I replaced my plugs, wires, and intake gasket. After doing this my car runs rough, i know i have a leak on my throttle body gasket. now my car has very slow acceleration, and it shakes more then usual and is louder. Any ideas?

Just noticed your posting and may too late - did you get this problem solved? If not....

If you already checked everything that was replaced, check all of the 5 million sensor and vacuum connections. My regular mechanic could not troubleshoot my 90 Eclipse' electrical problem so I spent several weekends learning about smog sensors, etc. Turns out for me, the O2 sensor wire insulation had come in contact with the heat shield and was shorting out. Fixing that made some difference. Last thing was the ECU (computer), (located inside the car, under the gear shift cover. Access is from the passenger side.) I could see 2 burnt Rubycon brand capacitors, replaced them and runs like new again.

Searching online, I saw that the Rubycon capacitors were known to have a problem, so I'm not a happy camper that I spent weeks checking all the wrong things when this should have been a recall item. I wonder how many people have bought a $600-1200 replacement computer when this should have been a factory recall.

Replacing the capacitors is not that big a deal. Don't try to unsolder the leads from the circuit board, though. Just snip them off and solder new leads onto the old leads. My leads ended up longer than I wanted and I had to wrap good with electrical tape to avoid any shorts.

"Several 1G owners have found that the electrolytic capacitors in their ECUs leak after roughly seven years. This problem is not limited to DSMs, engine computers or even the automobile world - many types of equipment suffer from similar problems, as electrolytic capacitors are commonly used in electronic equipment. "Excessive leakage can cause very troublesome damage to the printed circuit board (PCB) inside the ECU. This is very difficult to fix unless you have access to professional soldering equipment and tools. For those that do, they will find the repair difficulty on a par with any typical conformally-coated through-hole PCB repair. "

PS -- Reading about the capacitors, they were reported to start leaking after about 7 years (1997 for mine). That's exactly when the computer crapped out the first time. I replace the bad cap then. I didn't know about the faulty parts or I would have replaced all and avoided WEEKS UNDER THE HOOD! Thanks a lot Mitsubishi!!
