I was wondering if anyone could help me out? I am getting a loss of power in my 96 Hyundai Elantra. I can't seem to figure out why it is running like crap. When you come to a stop sign and take off if feels like it almost dies out and the same thing happens when you go over a dip. I tried fuel inject cleaner, spark plugs, spark wires,and I still don't know whats wrong with it. If anyone knows what to do please help me?
I have the same problem. If it makes you feel any better mine is a 2002. I agree with Hootie that the automatic trans has something to do with it. You would think Hyundai would've fixed this problem by now. I'm not saying that all Hyundai autos are bad. My friend from work had a 95 Sonata GLS with the 3.0 liter v6 and his auto shifted really good. It did have a perf/norm button on it so I don't know if that helped a little.
I've also have had a couple of diagonsitic tests and it says diffrent things. For example it is catching misfires in diffrent cylinders every time and is also saying a problem with fuel and air meter. I've been trying to fix the problem forever but have no clue. What do you think could be the problem and it is a automatic.
From what I understand Hyundai autos utilize "Fuzzy Logic" which is supposed to be adaptive to the conditions. "The available 4-speed automatic transmission uses computer control for optimum performance" <---- I wrote that word for word from the 2002 Elantra Guide that I got at the Philly auto show in 01. If it is the auto that is causing the extreme bogging I would assume that the pcm is the blame. I'm not really convinced that clearing the pcm will solve every problem related to the transmisson though. I would double check and see if the pcv valve is causing it as well. Just don't make the mistake of buying just any pcv valve like from Pep Boys. Try to get one that meets factory specs. I found that one out the hard way... :
ya that could be something if the cars reading a funny intake temp it will think its cold or warm and adjust for the air fuel ratio, could be so bad your is dumping not enough fuel for the air coming in giving you those situtations with the spark etc.. check this out if anything.
