poor acceleration by duncan21
Mar 17, 2005 (2:09 pm)
Reply
Hello,
I have a 1995 honda passport 2 wd with about 100000 miles. it is in pretty good condition and been having trouble with acceleration on the hwy. I have taken it to about 3 mechanics and have spent over 2500 trying to fix it. The mechanics cannot seem to locate the problem or give me a direct answer to my problem. the just keep telling me to bring it in and they will check it. and i get the vehicle back doing the same thing. what happens is i am on the hwy and when i reach around 50-60 mph i let up on the gas and my RPM"s go below the 2 on the RPM odometer and after that i have poor acceleration it hesitates really bad and i have to push the gas pedal alot to get up to speed. i did some research and i think it might be oxygen sensor but i dont know i just dont want to put anymore money into it. If anyone has experienced what i am going thru or have any suggestions please help me.

This is the second time this has happened. The first time after my husband drove the vehicle for a while keeping his left foot on the brake and the right foot on the gas when he came to a stop the car continued to run and after about 3 mile of this the problem corrected it self. Tonight after the vehicle started up fine, while driving home every time I went to slow down, the start spudder and finally stalled. This time when it stalled at first would not start idle at all, and then after I let it sit for a while it started, and idled for about 4 minutes. Also during this time I could be it in reverse and place it in 3rd with my foot on the gas or in neutral and the vehicle would idle. During 5 o'clock traffic I opted to have the vehicle towed home. The towed truck drive had this exact model and problem and suggested that it was the fuel pump. (Also my 81 year neighbor who came and met me said the same thing.) Any suggestions or has anyone else experienced this?

check engine light by elgru

I just purchased a 97 Passport and the the check engine light stays on. I hooked up my code reader and the code is P1406. Any ideas on this code, it isn't listed in Haynes. Thanks

The p1406 code indicates an EGR valve problem. Before replacing the valve remove it and clean it with carb cleaner. These valves get fouled up over time. Most of the time cleaning fixes this problem.

Your problem may be an IAC (idle air control) solenoid problem. But, there are many possible causes including intake manifold gasket leak or exhaust restriction. The point here is that your first step needs to be finding a reputable mechanic that knows these vehicles. People say that dealerships are overpriced, but spending 2500 bucks with no end to the problem can't be much better.

Rodeo CO emissions by pha_roah

I have a 2002 V6 Rodeo.
I just had the emissions inspection for the first time since buying the car 3 years ago.
The results seem excellent except for the Carbon Monoxide reading which did pass the test, but is double the average emission for vehicles in this class. Does anyone else have the same obvservation? is this normal for Rodeo's? or could something be wrong with mine?
Thanks in advance

1998 Rodeo 2nd Gear Grinds by nj2miami
Mar 20, 2005 (5:44 pm)
Reply
2nd gear has begun to grind whenever I am over around 1800rpm from 1st gear and anytime I downshift from a higher gear.
 
Put in a rebuilt tranny and changed the master cylinder.
 
Any ideas why this is still happening?
 
Thanks

If your CO reading differs significantly from other Rodeos then you might have a problem with the catalytic convertor.

CO can also be high if the car was not driven long enough before the smog test to allow for the catalytic convertor to reach optimal temperature.

That's true but I assumed (possibly incorrectly) that one drives to the testing location and does not have to wait long for the test to be conducted. Perhaps the original poster will elaborate.
