Hi guys!
My car will, on occasion, studder on acceleration from 1000 to 3100rpm. Above that it will studder less. This will happen when the engine bay gets hot and sometimes only when it's warm. My temp gauge reads between 1/8 and 1/4 depending on traffic.
It runs as if it's missing spark so I replaced the TFI module (on the dizzy) the car runs a little better but will still studder. Then I thought maybe it's the coil so I put in an Accel supercoil but it started to studder just the same (I admit it only did this after 25 minutes of driving in real hot conditions, normally it would do the problem after only a few minutes). The new coil was burning hot when I removed it (returned it to the store and put my old one back on).
I have problems with my IAC and TPS sensors since my engine will sometimes surge at idle and often it will stick at 2500 rpm (I quickly turn the engine off adn on to "unstick" it). I tried to connect my scantool but it keeps telling me I have a connection problem I don't have a CEL either. If I revv the engine with the clutch pushed in, it doesn't show any signs of missing spark but on idle I will hear a certain little "poof" as if one of the cylinders isn't firing.
I'm not sure what it could be, my spark plug wires (Ford Racing) and spark plugs (Stock Fords) are not old at all except for my coil wire which is God knows how old. I may get a new complete set of wires or just try and find a new coil wire to test that thing out. Also my TB was full of green and white crap, it was the gasket between the TB and EGR spacer that leaked coolant into the intake. I fixed that but I still have the problems.
Right now I'm real close to getting a performer RPM airgap intake, a double pumper 650cfm carb, Holley inline electric fuel pump, MSD dizzy, etc... to swap over to carb'd.
