Having problems with your 2004 Jeep Grand Cherokee ?

I just bought a 2004 jeep lardeo and told the guy I wouldn't take it unless it stoped. He said the auto tec said it was the emissions leak pump clicking in the drivers rear side. It passed the emissions test with flying colours. What can it be and how can I fix it. Now I have an engine light on and it says I have an large emissions leak and the mechanics can't find it.

Good day, maybe try replacing the gas cap or it may have a vacuum leak, you tell that to the mechanic and maybe he'll figure it out. hope this helps. have a nice day
What is the exact code being thrown by your jeep? How many miles are on the vehicle? How long have you owned it? Once I have more information I can assist you further.
Thank you,

Last year I was able to get my Emission test no problem. this year I have a problem. Original the car would stutter (starve for fuel) when we made turns or went up steep hills, but it still pass the emission test. We decided to make some repairs to fix the problem. We found that the gas test was full of mud and rust. We replaced the tank (brand new) and went to pull a part for a new fuel pump and assembly. Once everything was in the car started idling erractically. We thought it was the injector


I would look at the fuel filter first. When you replaced all of the fuel system components you should have replaced the fuel filter. This is one option. Another possibility is that the idle air control valve could be acting up. You should also ch ... Toyota Corolla

Car did not pass state clean air inspection tests due to high idle. I hear a vacume leak under the dash and I can change idle by manipulating vacume hoses iunder the hood attached to the carburator, but, I cannot locate the hoses under thae dash and cannot find a description or pictoral of the procedure anywhere on-line. Do you know where I can get this info. Also if I fix the vacume leaks will that fix my clean air issues?


The vacuum leaking sound that you may be hearing is from the expansion valves of the AC system. The vacuum hoses if fixed may help you achieve a cleaner emission but proper timing, good fuel and air mixture and a working ignition system is also a fa ... Chrysler LeBaron

My service (with a wrench) light has come on with my 200 pontiac sunfire along with my ABS light and Trac light. I am not sure if I will pass emissions because of this. What can I do as a temporary fix until I can take it in to get checked out so that I can pass my emissions test.


ABS and Trac light are both on because of a anti-lock brake system issue. This will not effect the emissions system of your vehicle. You probably have a bad wheel speed sensor but there is no way to tell without plugging in to your ... 2000 Pontiac Sunfire

I saw your post on this and had the same issue with my 2002 Camry SE. When I've taken it to the dealer in the past, they look at me like I'm crazy. What should I do? Also, my car now seems to be burning oil. Is this an expensive fix? Should I go to a Toyota dealership or should I go to a trusted mechanic? Car can't pass emissions test 2 years in a row. I'm trying to consider what will be the more cost effective option, to fix or lease a new car. Gratefully, - Me

Recently my check engine light came on. When I had it checked I was told that it was something to do about gas, the technician said many times it is just a loose cap, which he said seemed to be on tight. He turned it off and the next time I filled it it came back on again. When I fill it all the way I can smell gas for a short time. My biggest concern is that I have to get my emissions test soon and I fear my truck will not pass. I was hoping to get just one more winter out of it, so I don't wan

Seem to have the same problem as lindag1003's with my 2001 Sentra. No heat in the car, or heat on passenger but not on driver's. Engine temp guage went above limit. Coolant was bubbling. Mechanic checked it out- topped up reservoir, looked for leaks, test rode it, fine now. Said if problem happens again, it is likely the gasket, which is expensive to fix. Could this affect the engine as well? Have almost 192K on the engine. Is it worth it to spend at lweast $1,000 and upwards to fix the gasket,
