Surging when hot, ok cold

I have a 2001 Hyundai Elantra that surges to the point of almost being undriveable when the engine is hot. No loss of coolant has been experienced and no fault codes stored in the memory. Any ideas please???

Check your Idle Air control Valve and your EGR valve. Most of the time these will not set off codes but will give you problems like this and are easy enough for a none mechanic to fix it

Same as ALL vehicle issues

Put a scanner on it & check for codes
& look at data,don't use it like that, until
you know the issue

Have a shop drive it for 25 miles & record data
& wait for it to act up,then diagnose the problem

My 2004 Hyundai Elantra surges and jumps gears


You got ripped off by the mechanic. A good mechanic can pinpoint the problem by using a scan tool. Take vehicle to autozone or similar and have it scanned for codes this will give you a idea what is wrong. I believe the problem is exhaust related because of the blinking light.

My 2001 hyundai elantra (automatic) loss power while driving


The check engine light usually comes on when there is a faulty sensor. or circuit. Sounds like you may have a faulty throttle position sensor. It would be best to have engine codes read to pinpoint exact problem area. Many part stores do this for free.

I have a 2001 elantra automatic. Hesitant from a cold start


Without knowing what the fuel pressure is, no one can say for sure. You'll need to check that. If you find there is a fuel pressure issue, you'll need to isolate the cause (wiring, connectors, pump relay or the pump itself). You will also want to inspect/examine the intake air hose, filter & vacuum lines to eliminate those things as possible causes. Additionally, you might simply have a throttle position sensor which is malfunctioning/going bad. You'll also want to scan your OBDII for any trouble codes which may have been set and which could help narrow down your search for the cause.
