i have a 5 spd, 99 civic ex, i just had someone chang the timing belt, put a new head on, and fix some ground wires that were off. now my car is idle surging real bad, and after driving for 10 minutes or so, the following begins to happen. when sitting at a stop light or whatever, my car's idle goes up and down 1 or 2 hundred rpms very fast so it sounds like its sputtering or something. also, when driving, the accelerator becomes very touch. when i let off the gas the car jerks, and when i press the gas again it jerks. my whole car starts shaking real violently if i'm driving at a low speed and pressing the gas, so i have to downshift, and drive at high rpms. i don't know if it's off time, or what is going on. please help.

Have you checked for a vacumme leak? That's what I think would cause the idle surge

I had the exact problem with my 1999 Honda Civic EX turned out to be TPS sensor located behing the Throttle body it was bad. What you can do in the mean time is disconnect the tps cable and it wont give you that problem. It could also be a number of things, some of the things other people might tell you is to check for vaccum leak or iddle control valve. Good Luck!

to be honest i don't know a lot about working on my car at all. i'll look those things up and try that though. would that also explain the very touchy throttle?

live and learn(<im quoting a man that showed me about hondas)i suggest that you check it out first,do a cel check any autozone or advance auto parts will check it for you since your car is obd2,see what codes you got and start there

i checked the code for the cel, they were for the idle air control valve. i also saw that an animal had chewed up some wires in my engine bay. one of which being the ground to the idle air control valve. would it be worth getting a new wiring harness? or just taking the time to hunt down the exact problem in the wiring?
