    Oil Presssure Jumping Around

    I would assume (not to mention hope) it's the sending unit, the car seems to perform good at all RPM ranges so I'm hoping this is the all so elusive, easy and inexpensive fix!!

    Oil Pressure Guage Needle Jumping Around

    Hello, I posted this in the SVT forum but thought I'd post here as well since there seems to be more activity in this forum.. I own a new to me 1997 Cobra, when I start it up the oil pressure reads just to the high side of the gauge mid-point, when I drive moderatly no change, when I start to...

    Oil Presssure Jumping Around

    I own a new to me 1997 Cobra, when I start it up the oil pressure reads just to the high side of the gauge mid-point, when I drive moderatly no change, when I start to rev up past 3500RPMs or so, the needle starts to jump around then move towards the low side of the gauge until I shift, then it...

    Another Speedo Gear Question

    Thanks for the input, I found a formula somewhere and I think my speedometer variance is 15%, the speedo gear I used should correct for the change from 3.27 gears to 3.55, leaving the unadjusted variance the difference between 3.55 and the 4.10's I installed. I think I'll have to breakdown and...

    Another Speedo Gear Question

    Sorry, I have an automatic, all of the guides I've been able to find indicate that there isn't a speedo gear that will correctly compensate for 4.10's, the 23 tooth gear I had put in is supposed to be the closest. Using one of those gear calculators, it came out showing I needed a 25+ tooth...

    Another Speedo Gear Question

    Sorry, I searched but couldn't find an answer to my question, so here it is. I have a 98 GT convertible and just changed to 4.10 gears, I had a 23 tooth speedo gear installed at the same time. Driving home I had my wife follow me and give me her speed and it appears that at 80 MPH on my...

    4.6 versus 5.0

    Well, just saw pictures of the car, looks in good shape, yellow exterior with a white top, but red interior. No offense to anyone who may like the color combo, but yellow exterior and red interior is a no go for me no matter how few miles are on the car...thanks again for the input, interesting...

    4.6 versus 5.0

    Sorry, I didn't specify but my 98 is a convertible also, the 94 has only 30K miles, my 98 has 115K, hence the dilema..

    4.6 versus 5.0

    Thanks for the input, the plan would have been to sell the 98 which would more than make up for the cost of the 94...but then yesterday my wife told me of her plan to take the 98 herself if I bought the other...indeed leaving me in the hole financially...nothing wrong with the 98 although I'll...

    4.6 versus 5.0

    Not sure what forum to post this in, but I thought I'd try here. I MAY have an opportunity to pick up a 94 GT convertible with extremely low miles for under $4K, I currently own a 98 GT, assuming all else is equal would the 94 GT with low miles and a 5.0 be a better choice than my 98 with the...

    Another Gear Question

    Thanks for the responses! I had never heard/read anything about the kind of issues noted in my post, and since I have a handheld tuner I figured I could change shift points and the rev limiter if necessary. Anyway...thanks!

    Another Gear Question

    Sorry to beat a dead subject...but...I have a 98 GT automatic with the four-speed transmission 4R70W. I want to put 4.10 gears in it, but I've been told if I do that with the transmission I have that I'll hit the rev limiter before I can even shift out of first gear, with the only solution...

    New wheels installed...steering seems off? **Continued thread merged in here**

    I had a similar issue, switched from the stock tires to 17X9 with 275's on the front and it seems to drift to one side or the other. The tires are new and I had it realigned, even though it was aligned less than a year ago, everything is good, but it still seems to drift to one side or the...

    Power Loss with CAI

    I have chrome cobra replica's. Thanks for the thoughts, not gonna change the wheels/tires cuz I like'em, even if it does bog me down a bit, but, I will clean the MAF and see it that helps. If not I'll toss the stock air intake back on and see if there is a difference.

    Power Loss with CAI

    Hadn't thought about the impact of bigger tires/wheels, and they are definitely bigger, 17X9 in the front 17X10 rear with 275's up front and 315's in the rear. Since I did both Wheels and CAI the same weekend I couldn't distinguish if the issue is related to one over the other. I'll probably...

    Power Loss with CAI

    Ok, here's the deal. My car (98 GT) has been running as less than my normal standard lately, kind of sluggish without the "pop" I've come to expect. My mechanic can't find anything wrong. In trying to reconstruct the timing of when the issue started, it seems to go back to a weekend in which...

    Diablosport Predator

    ============================ I am on the most current version, performance on the old version was actually better. I'm inclined to think its a mechanical problem, but I don't know what, my mechanic can't find anything and says the car feels fine to him on test drive. But...I know it's just...

    Diablosport Predator

    I own a 98 Mustang GT with minimal mods and have a Predator tuner, I run Exxon 91 octane fuel. The Predator tool comes with tunes for 93 octane (written for a minimum 91 octane) and 87 octane. When I run the 93 octane tune (even adjusting the spark retard) it runs terrible, flat, no...

    Thanks, I was messing with my handheld tuner and reset the codes a few days ago, guess I haven't driven it enough yet.

    OBDII Help

    I've got a 98 GT Convertible and am using a Diablosport predator. I was messing with the predator and I went to the option titled reading trouble codes and it shows P1000 unable to complete system test, or something like that...anyone know what the deal is with that? The check engine light is...
