idle

If i had a vacuum leak, would not the boost gauge read 0 in. Hg at idle? It reads 20 in. Hg now, but Idle seems rough and I'm trying to rule out vac leaks or IAC, which i have not tested yet. Also, the cruise control seems to be delayed in engaging, like it takes 2-3 full seconds or more before...

So i have a 99 cobra (terminator engine) built with diamond pistons, slightly higher compression. I recently started having an issue where it will be full rich 10.0 on the wideband. Cruise around and itll go back to 14.2-14.5 while cruising around, then ill apply a little throttle to get over a...

Ok, kind of long description but trying to be as throught as I can. My recently acquired 98 Contour SVT has a bad problem with throttle hang. It's throwing a check engine light for code p1120 (tps, ratch too low) and when first starting it up it runs ok but seems as it warms up it gets...

Hi all, I am looking for you opinions on aftermarket Coil on Plugs. From what I have read, everyone seems to split on the aftermarket vs. factory COPs in this particular case. I understand that the stock COPs can support 800+ horsepower, and that they'll do it just fine, but does that...

Hi from Okinawa! Well I am probably the only 1996 Cobra on this Island and I am looking for a little help from you guys back home. I picked up this car with 57,000 miles and have done the simple tune-up items such as plugs (AL 764) Oil/PCV/Idler/Tensioner/MSD Coil packs/K&N Filter/fuel...

Hi everyone, new to the forums. I own a '00 GT automatic and here's some background into the situation. Started a year ago, my brother in law rebuilt the motor and in the process of doing so, had installed Comp Cams 262AH stage 1's. A year later after the rest of the work I have the car back...

Does anyone know how to test a MAF sensor? I have a stock MAF sensor that I believe is going bad, or it may even have already gone bad. I would like to test t prior to purchasing a new one. I have a 2011 GT500 that was running for months at an AFR of 11.8 at WOT and the AFR of 14.6 idle...

I feel as if I’m dealing with 3 issues here; possibly related, but I am running out of signs to use for trouble-shooting. The first problem is a low, rough idle that sounds as if my ’04 cobra has a pushrod motor with a loping cam. The second problem, while I originally thought was independent...
