Guys, hard situation. Death in family, 350 miles from home and tools. On way up here felt a lot of vibration from front end. Figured it was new tires lost a weight, just need to rebalance. Then at times i noticed loss of power, flat spot in power curve. Vibration seemed worse at times, could it be road surface I wondered. For sure it was worse at 70+ mph. Failing fuel pump wouldn't do this right?

Then I began to wonder if a misfire could cause this feeling. Hopefully I'm being paranoid wanted to ask your opinion before I face the 350 mile trip home .

FWIW temp was very good entire ride. Gas mileage never better 25+. I do have a code reader, will try to hook up later. Thanks for your thoughts. Hopefully this is nothing to worry about. Guess I'm trying to diagnose by inference . Your thoughts are welcome and appreciated.

my first thought is a blocked fuel system, which is usually the filter. Changing the fuel filter is relatively easy compared to other maintenance items, and easy to cross off a list of potential issues. If you don't have any codes being generated, then I'd suggest changing the filter. since you are on the road, your options are limited. Were I in your place I'd be very tempted to drop off the car at a reputable repair shop and get a rental car for the rest of your journey. That way you can focus on the family issues, and deal with the car later when it is more convenient.

A steady misfire will throw a code and the CEL will illuminate. Intermittent might not.

 

Sorry to hear about your family issues.

The Timing for your 350km trip in a busted Jag couldn’t be worst. Not a lot of options and driving the car could cause more damage than it’s worth.

Not an easy fix considering your family situation. Park it up. Deal with it later

 

Thanks guys. All seems ok 2day at low speeds. Bet it's going to be the filter. Lord knows I've seen that before, explains it perfectly. Will likely not get to it before I'm home tomorrow. Was probably just over reacting because of the situation.

From the bottom of my heart - thank you. It's nice to know I can count on you / that we help each other out.

Glad to hear the car seems better, and very sorry for your loss.

If eventually car does through a misfire code, you could try swapping the coils/injectors to see if the code moves cylinders. Pretty easy to do for early cars like yours and mine. I had a super intermittent misfire for a while and troubleshot things that way. I basically had no symptoms through. My first thought with the lean code was a fuel issue like zray said.

Sending well wishes to you and the car...

 

The more common misfires (such as coils) put the MIL on before you feel them at all so the filter or some other restriction is a fair bet.

Sorry to hear the bad news.

 

John,
Just want to add my condolences to you and the family.

^^ I also send my condolences to you and your family for your loss....

 

Agreed

 

Thanks all. I made it home ok. Looks like the main culprit was some bad gas. Filled her up (+75% of a tank) at Shell on Cape cod and drove home without misses or flat spots. Will change filter tomorrow as precaution.

This is closed. I appreciate your well wishes too.

My condolences to you and your family. Glad the return went well and marking this as resolved
