04 VW Jetta 2.0 manual not going over 3000rpm
Asked by SkylerCasas Mar 23, 2018 at 12:34 AM about the 2004 Volkswagen Jetta
Question type: Maintenance & Repair
I just got an 04 VW Jetta 2.0 manual. It has roughly 180xxx-
185xxx miles. It will not go past 3000rpms in any gear. It
also requires you to barely even push on the gas peddle for
it to slowly gain any speed. Anything over barely pushing
the gas peddle and the car won't gain any speed it jus loses
speed. I've already replaced the CPS and that didn't do a
thing. Any other suggestions? Has anyone else experienced
this problem??

Possible plugged up catalytic converter.

From research of reading other forms I've heard a few say that replacing the MAF fixed the problem. Should I check that first before servicing the CAT?
That is up to you. A MAF should be cheaper than the cat but a back pressure test on the cat is where I would start.

If the pressure is low or insufficient is there a way to clean/fix the CAT rather than replace it??
You could try a cat cleaner or snake oil. Not much difference in my opinion but if you can spare $10 go for it.
BTW - if the pressure is high the cat is bad. Low is good.

So I unhooked the battery for 30min as suggested to reset the computer and get it out of limp mode. Upon hooking up the battery the car won't start. It seems like the fuel pump isn't coming on now.

Turns out I fucked up the motor. Wen't to replace the belts and didn't get the TDC right. Locked up the motor n froze it.. What other size motors besides the 2.0 will fit in my 04 VW Jetta??
