Need a small tune up

Cricket · November 12th, 2009, 12:16 AM

Just had a 100 mile trip today and only averaged 22 mpg. Didn't even go over 1600 rpms really for the whole trip. 55 mph on cruise control. Now I know the guy before me really didn't take good care of the car, and I know I need an oil change. Aside from that I'm going to change my fuel filter, and possibly spark plugs. Well I will for when I get a smaller pulley. Anything else you guys can think of for a small tune up to get her running the way she's supposed to again with better mpg? Tires all had good air pressure in them.

good luck with the fuel filter

its really not that bad its just not easily accessible. Other then what you mentioned might I add a new air filter

I was thinking we could get it done when we do the swap

Make sure the plugs are good. That's a big one.

Cricket · November 14th, 2009, 04:42 PM

I have a feeling they aren't. it takes a little longer for the car to start but everything is ok. And when it does start it like an old man standing up it starts slow then its good to go.

Do a fuel induction service.
Clean or replace the air filter.
Change the plugs. I use Autolite AR103 on the stock pulley and AR94 with the 2.8
Do you have a good alignment on the car?

Cricket · November 14th, 2009, 08:48 PM

I need an alignment done.

I'm planning on getting a smaller pulley soon so should I go ahead and get the colder spark plugs, and will they be ok to run on the stock tune?

C MY 4D · November 15th, 2009, 03:23 AM

Yeah they should be fine, especially if you jump on it often.

Cricket · November 15th, 2009, 10:32 AM

ok just wanted to make sure before I got them. I'm planing on changing the plugs, the fuel filter, getting the JLT carbon fiber rai(I'd rather do that then get a filter), and I'm going to change the oil today.

Cricket, what gear where you in to do 55? What rpm? With my stock gears, my mileage at 55-60 is considerably worse than at 70-75.

Cricket · November 15th, 2009, 10:51 AM

sixth

I'll try it sometime, but I can tell you...everything I am replacing...needs to be. The guy who owned it before me...did not take care of the car at all.

M L Struck · November 15th, 2009, 11:06 AM

Try that same trip and if you can try and run the car at around 2k rpm, 1600 is lugging the the motor a little bit.

UWISHU1 · November 19th, 2009, 10:44 AM

clean the mass air meter too

AzSonicSnake · November 19th, 2009, 10:51 AM

22mpg? damn. i'd kill for that in my cobra. think my best to date was like 14-15.

Cricket · November 19th, 2009, 11:15 AM

stay off the loud pedal...but also mine is stock performance wise. My filter is absolutely filthy, and just found out my MAF housing is cracking by the bolt holes. Guy tightened it way too much around the filter.

dirty filter and un metered air through your cracked MAF housing is the best combo for good MPGs

Cricket · November 19th, 2009, 11:19 AM

yep. I'm gonna replace them both.

After I replace those, and my rotors and pads. I should be good to go.
