Infinity G20 1995 Loses Power while driving but "runs" good?

Question

I was driving down the freeway and my G20 just lost power (no sputtering), then, as I pulled off to the side to exit it appeared to be OK so I pulled back onto the freeway. After another minute it lost power again so I pulled off at the next exit where I pulled over - the car seemed to be purring normally (so I thought maybe it swallowed a bad chunck of gas). I pulled back onto the freeway. Two exits later I could feel the power leaving again so I pulled off on the next exit. As I was driving down the road trying to get to a car repair place I had been to before it started losing power again. I drove on the shoulder surging then rolling repeatedly as the power went and came back. I made it to where I cut across to make a left hand turn - I was able to cut acroos to the turn lane, wait at the light and turn to make it to the car place. They looked at the car and found nothing unusual - they replaced the air & gas filter. No prob with injectors/firing. Still not resolved... HELP

Answer 1

i own a repair shop,in Tennessee,and its possible it may have a bad fuel filter on it, or the catalytic converter may be getting a little stopped up on it,they will still run smooth just not have as much power as they once did,i always recommend you take it to auto zone and have them scan it for free,and they can tell you if it has any trouble codes in it and if so what they are,and how to repair them also,there good at finding them,and this way you,ll now for sure,instead of just replacing parts on it,,good luck with it,i hope this help,s.

Answer 2

Possibly faulty "knock" sensor.
What that does is retard the timing durring acceleration, and under normal use to reduce engine knock, or detonation.

They are difficult to troubleshoot, and most people aren't familiar with them. Aslo, it may not show up on a scan of engine codes.

Try this first, fill up with top grade gas. 91 octane if you can find it. The higher octane has more chemicals in it to reduce engine knock, and keep your timing advanced to increase performance.

If after trying higher octane, it continues, you may want to have it checked out further.

Also, check the basics, engine oil, coolant, trans fluid, etc.

Good luck.
Did you buy crappy gas? Low octane?

It sound like its your fuelfilter its easy and does not cost allot of $ you should start there and if you have a check engin light take it to pepboys and they can checkout for $75 or Auto Zone they will doit for free. and thats any auto zone. true that and have some one site under the car when you start the car and see if you hear a nosie from the tank if so that mean your pump is working right and thats good news.

even as avert equipped the Neon that they had a outstanding concept about putting inline fuses in them. They were an exceedingly undesirable concept. Neon has a huge situation with that. The inlines blow out and no skill is transfered to the run or initiate cycle to starter. consequently engine is lifeless. lighting fixtures run on a seperate circuit so that they don't have any situation operating
