OK, guys, I need your help, Im losing plot with my coupe. I have a 51 reg 2.2 coupe. The engine is a z22se. Just had it back from garage after having new head cylinder, new thermostat, oil, filter and antifreeze.
So you would expect it to run better than when I took it to them...WRONG.
Guy said they had checked faults but none came up but warned me at desk to keep eye on fact when you turn car on you have to dip accelerator or the car struggles to start. Said the head may need to just settle. Also its really rough at idle. My moms 1985 pug idles smoother than my coupe at mo. Driving its fine but at idle which is around 750rpm the car shakes and interior dash lights flicker. Also the dreaded white smoke is back, and lots of it but only at idle.
Just tried pedal test and all thats happening is engine light stays on and so does the electronically controlled engine cooling light. Also when I took it up motorway the temp gauge dropped to what it is when car is off. Im noticing aswell that if I over rev car my petrol needle literally drops a bit...Ive searched through the forum and basically it seems it could be
Timing chain out
Idle control valve
Coolant Temp sensor
I really want to love this car but it just seems to keep going wrong. Would love it if anyone else has solved this problem. Im taking it back to mech tomorrow but would love to have some ideas to help them along way.
Thanks for reading
