HELP!

[Duck Vader]

Well I took the video. I will post it when I get home. It hesitated really bad at one point, but did pretty good the rest of the way. I am going to autozone tonight to get the free check ups they offer, pick up a compression gauge and rent one of their fuel pressure gauges if they have one.

How do you use the fuel pressure gauge? I know how to use the compression one.

[Duck Vader]

I think I figured out how to use the fuel pressure gauge....thanks for you help....


ANYWAY


anyone else have a comment on the video?

Like I said I will post the new video of my driving it tonight. I am going to autozone to pick up some stuff after work and get that free test.

Duck, it's hard to help someone when they don't take your advice.

2 people now have mentioned it's your exhaust and yet you are testing fuel pressure. I know you're just "eliminating possibilities" but think logically for a second:

You have holes in your exhaust. They are known to cause the issues you described. What might the problem be?

[Duck Vader]

I just want to make sure it is not something else. That is going to be a few hundred to fix the exhaust. I don't want to spend that money and that not fix the problem. Sorry if I am coming across as rude or anything. It is just that I don't have money to just throw at it till it is fixed right now.

I'm sorry mono.

Well here is the video that I took while driving. Play close attention after the 3 minute mark especially and then again after the 9 minute mark. Driving to work it only did its thing at the one 3 minute part, but on the way home, it did it the whole way. I stopped at autozone and they said they don't test the things listed online and they dont rent out the tools i need. I will test my TPS tonight. I can no longer drive the jeep in its condition.

Please watch the video and let me know if you think this is an exhaust problem for sure.

Sorry I have been so pushy with this, I just want to make sure I figure out the problem.

For all those that have helped, I would like to thank you. I really appreciate all your help.

Why don't you just metal duct tape the exhaust and see if it works, that'll hopefully tell you for 5 bucks whether the next 200 are worth spending, at least.

[Duck Vader]

I read your post bleed. I might try that but I have a few other things according to jeepforum that could be wrong.

Tonight I am going to test the TPS, clean that IAC, check the O2 sensor on the downpipe and fill up the tank with new gas. If none of that fixes it, I will take off the Cat and see if it is bad.

Thanks again...and I guess I have to say this....thanks for your input bleed.

I don't expect to be thanked for every bit of everything (helpful) I say, it's just nice once in a while

[Duck Vader]

anyone actually watch my google video?

[BleedScarlet]

the video looks like normal driving to me

[Duck Vader]

you have sound?

so far about 5 people on jeepforum are now saying either bad cat or fuel filter

[Duck Vader]

also, at those times, watch the rpm's and speed, and listen closely.

[BleedScarlet]

[quote=""Duck Vader""]you have sound?[/quote]
ah, no not today. Took my headphones home last night to fix the jack and left them there...
well, from a purely visual perspective, i see 50 MPH at 2-3k rpm...which is okay to me!

Is the only real problem the sound, or is it acting really differently? From the way you described it, i was expecting to see you hit the gas and the car would stall, like sparks were just...not happening (Can happen, happened to one of my cars before.)

[Duck Vader]

at the 3 min mark you can see the rpm really drop then as i am hitting the gas and the rpms shoot up, i am not accerlerating fast at all until i floor it and shoot the rpms way up. Then at the 9 mark i am not hitting the gas during the first turn or at any time after the 2nd turn. If you heard the sound you would be able to tell alot better.

[Duck Vader]

should I change the fuel filter too?

I know exhausts are expensive which is why I recommended you get a patch kit. Cheep check & temp fix till you get the $$ to replace the pipes.

[Duck Vader]

im suprised that on Jeepforum people are actually helping. about 85% have said it sounds like a cracked manifold and bad cat. the other 15% are saying it might be fuel.

[Duck Vader]

I am going home and working on this. I hope I figure it out tonight. Thanks again to those that helped.

[Duck Vader]

OK, TPS is fine, IAC is cleaned and I can't get the cat off without cutting it. I also put gas in it and i did not check the O2. The more I thought about it, I am going to have to replace the exhaust anyway.

When I had my wife rev the engine and I felt the exhaust coming out of the tail pipe. When she first reved it, I could feel the air coming out a bit harder than at idle, but it was a steady flow. It pretty much came out at the same speed as idle since idle is pulsing really bad. I am guessing something is clogged. I will more than likely now replace the manifold back.

When we were almost done a check engine light finally came on. Since I do not have an OBDII scanner, I did the ol' home remedy version of holding in the odometer reset button and turning the ignition from on to off 3 times. I came up with code 2.3 (23 I am guessing) which according to Hanes is Intake Air Temperature Sensor.

Would a faulty IATS cause my problems?

[Duck Vader]

According to Hanes it senses the temperature of the air entering the intake manifold. The PCM uses this info to control the fuel mixture.
