Shudder Shitty Shudder

[Identity Crisis]

Ok this is driving me MAD.

The car at 60KPH and around 1700 RPM shakes and shudders like a SOB! The RPMs will become erratic.

If I nail it and get it over 60KPH the shudder goes away.

Any Thoughts?

So far I am thinking there is an issue with the IAT and or TPS. HMMM

Well I used a complete can of Throttle Body Cleaner on the IAC intake hose and then I took it for a run. So far it has not shuddered at all, but we will see as the week goes on.

Next step is to try SeaFoam and then an IAC motor.

might be an ignition problem starting to surface. Check plugs and wires.

Nope not plugs and wires. It was doing it before I built my wires, changed out my coils and plugs.

But two days going now and no shudder. I may have solved the problem.
