Default Help - car not running right after installing starter

I had to remove the starter in the car and then put it back in, but now the car isn't quite right.

When revving, there seems to be a 'cough' (best I can describe it) and then it revs. So a slight delay and then revs. Mywife says the car feels like it is down on power, or that itis towing something. The only things that I had to remove to get at the starter is the airbox, throttle body and plenum. I made sure the throttle body was plugged back in and the maf. I also made sure the vacuum lines that plug in to either side of the plenum are connected. There is nothing else I would have tinkered with to get the starter out.

Any ideas?

Sounds like a vacuum leak to me . Double check all clamps on the plenum .

That's what I figured, but I made sure that the lines poked through.

Cant hurt to check again.

Im guessing the rubber boot for the plenum is not fully on. Its difficult to get right and even though u r 100% sure its i correctly, check again. It helps to use an inspection mirror.


U could also have cracked the oil fill tube. Sometimes just looking at them wrong causes a split.

Agree with comments above, sounds like a vacuum leak and the plenum sleeves are the most likely culprit. Super critical to get them seated and keep them seated as you tighten the screw clamps. Will make a big difference in how the engine runs if those sleeves are not just right.

I went back and reseated the plenum. Everything seems better now.

Thanks guys
