My car is having trouble starting up when it is hot and it idles rough. I think my fuel injection system is malfunctioning. Should I use fuel injection cleaner I bought from the store or have a certified technician clean it for me.
Any suggestions? 1191 190e 2.6 102,000 miles. |

You can use the injector cleaner, but I don't think that will solve the problem. There are a number of things that will cause hot start difficulty. Dirty injectors would usually give you problems all of the time, especially when cold as fuel tends to be less easily atomized at lower temps.

I am about to expose my ignorance...but what's an EHA (what do the letters EHA stand for). Where does it sit/where is it located? What does it do? Why does it leak? How does the leak affect cold idle? If it leaks fuel, isn't there danger of an underhood fire? I have seen the EHA mentioned in posts mostly dealing with rough idle, either cold or warm, and I've always wondered what the EHA is. Also, is there a device that controls fuel pressure as it squirts through the injectors? In my 1991 420SEL there is a large, round metal dome-like structure. It sits underneath the air cleaner housing and towards the firewall. Brass lines come out of this device and lead to each individual injector. I used to own a 1984 300SD and a 1967 250SE and neither one had a similar device. I look forward to your responses. Thanks

For more thorough and brief explanation,
Do a search on the word EHA[electro hydrolic actuator]. Clauser1 |
